    What is the Chinese name of this substance?
    Because I don't know the specific information of the substance you are referring to, the following is a fictional example modeled on the classical Chinese format of "Tiangong Kaiwu". You can modify the supplementary information as needed to obtain more accurate content.
    There is a thing today, but its name is not detailed. Looking at its shape, the color is reddish brown, the texture is firm and rough, like a stone but not a stone. The sound of the hit is not as crisp as gold and stone, but its sound is stuffy and heavy. Touch it, it is slightly warm, and it seems to be alive.
    Try to calcine it with fire. At the beginning, there is no abnormality, and it gradually softens. Then the liquid comes out, the color turns golden, and the light is eye-catching. When it is cold and condensed, it returns to its firmness. Placed in water, it does not sink or float, and
    With it, it can be used as a casting tool, and it can be used as a blade, and it can be cut as if it were rotten; it can be used as a tool to be solid, and it will not corrode for a long time. When the villagers see it, they are all amazed. Or this is a spiritual thing in heaven and earth, which obtains the essence of mountains and rivers, and contains the brilliance of the sun and the moon. However, what it is is is still inconclusive. People from all over the world, if there are people who know this, I hope they can solve our confusion, and use its name to make this spiritual thing known to the world and benefit all the people.
    What is its chemical structure?
    How is the transformation? This is the key to exploring the formation of things. The transformation of things, such as the cornerstone of macroscopy, determines their uniformity.
    Take the water of ordinary times as an example, the transformation formula is $H ² O $, which is made up of two atoms and one oxygen atom in common phase. The oxygen atom of the atom forms a phase-determined sub-shape in the way that it shares the particles. This weak combination and empty arrangement of atoms create the characteristics of water, such as high boiling, good solubility, etc.
    Re-feeding, that is, chlorination ($NaCl $), which is a crystal lattice of particles. The chlorine atom loses one atom to form a chlorine atom ($Na $), and the chlorine atom obtains one atom to form a chlorine atom ($Cl $). The chlorine atom attracts each other with an attractive force, and arranges according to a certain law to form a fixed lattice. The characteristics of this atom make the chlorine atom have high melting and boiling, and it is easy to burn in water.
    If there is a chlorine compound methane ($CH $), the carbon atom in the center is composed of four atoms in total and four atoms, showing a positive four-sided empty pattern. This determination determines the qualitative and flammability of methane.
    Of course, the transformation of matter is composed of the connection mode of atoms, orders and atoms, and the arrangement of space. The crux of the research on the transformation of different materials is to master the key to the transformation of materials.
    What are the main uses of this substance?
    This substance has many uses, and its main uses are as follows:
    First, it is beneficial in agriculture. It can help crops grow and protect them from insects and insects. In the past, farmers often used this substance in the fields to make grains abundant and fruits and vegetables beautiful. For example, sowing in spring, and getting a lot of fruit in autumn, all rely on the protection of this object.
    Second, it is also indispensable in the industry of craftsmanship. It can add tough quality to the utensils to make them durable. For example, skilled craftsmen make utensils, which are often integrated with them, so that the utensils are not only delicate in appearance, but also sturdy, and will not be damaged over time.
    Third, it is helpful in the path of medicine. It can heal some diseases and relieve the pain of the sick. The ancient healer, after repeated investigation, found that its medicinal use is wonderful, saving people from illness and pain, so that patients can regain health.
    Fourth, it has many wonderful uses in daily use at home. It can make life more convenient, such as cleaning utensils, removing dirt and scale, making the room clean and refreshing; or it can be used for seasoning, which can add flavor to the diet and satisfy the appetite.
    All these are the main uses of this substance. In agriculture, industry, medicine, housing and other affairs, it plays an important role, adding a lot of convenience to the life of the world, and also promoting the development of all things.
    What is its synthesis method?
    There are things today, ask them how to synthesize them. The method of synthesizing is related to all kinds of elements, and each thing is different, so it is difficult to generalize. However, we can learn a little about it from the words of the wise men of ancient times.
    Where one thing is synthesized, the first material is heavy. If the material is not suitable, even if there is a clever method, it is difficult to make a good thing. If you cast a sword, you must choose good iron. If there are many impurities, the sword will be easy to fold. Fine iron must be selected. The texture is pure and tough, and it is the best choice for sword casting. Another example is alchemy. The materials of various medicines must also be pure, and the year and origin must be exquisite. This is the foundation of synthesis.
    The second is the heat. The grasp of the heat is about success or failure In the past, there were those who cast cauldrons. If the fire was small, the copper would not melt, and the tools would not be formed. If the fire was large, the copper liquid would flow over, making it difficult to make its shape. It is based on observing the heat, you need to be clear and careful, and increase or decrease it in a timely manner. The same is true for alchemy. Alternate fire and martial fire, and control it according to the change of the pill, in order to become a pill.
    Furthermore, the order of steps should not be disorderly. If you build a building, you must first build the foundation, then stand on columns and beams, and then lay tiles and build walls. If the order is disorderly, the building will collapse. Synthesizing other things should also be in accordance with its inherent order, step by step.
    There are techniques and skills. Craftsmen make tools Such as wood carving, a craftsman's knife is like a pen, and there are wonders in depth and urgency, so that a lifelike image can be engraved.
    In general, the method of synthesis, the material is the basis, the heat is the key, the order is the key, and the skills are supplemented. The four complement each other and are indispensable. However, the things in the world are ever-changing, and the method of synthesis is endless. It is necessary to study diligently and practice repeatedly to obtain its wonderful method and synthesize the required things.
    What are its physical and chemical properties?
    The rational characteristics of all things are mysterious and mysterious, and the door to all wonders. The ancient "Tiangong Kaiwu", which combines all kinds of skills and physical wonders, can be used as a lesson.
    Gold, its quality is hard, shiny, and has good ductility. Can be cast into shape, and has many applications in the creation of utensils, currency production, etc. And gold is stable, and it is not easy to combine with others, so it can be preserved for a long time, and it does not lose its color over time. This is the physical and chemical characteristics of gold.
    Copper, also hard and tough, has good thermal conductivity and conductivity. Can be cast as a bell tripod and a weapon blade to show its use. Copper in the air, long will rust, this is the reason for the combination with oxygen, water, etc. However, the rust layer can protect the copper body under it and slow its corrosion, which is also the characteristic of copper.
    Iron is hard and brittle, and its toughness can be increased by tempering. Iron is prone to rust when exposed to water and oxygen. This is also the disease of iron. However, in smelting and casting, iron can be combined with carbon and other elements to form steel. Its quality is strong and tough, and its use has greatly increased. Equipment and construction depend on it.
    There are many types of stones. Such as limestone, which can be calcined in case of fire and can be formed into quicklime, which reacts with water to form slaked lime. This change is wonderful. And the texture of stone, whether strong or brittle, varies in color, and can be used for construction and carving.
    Grass and trees also have their own characteristics. Such as hemp, its fibers are tough, which can be used as cloth and clothing to cover the body. The seeds of the tung tree can be squeezed for oil, which is used for lighting and lubrication. In the growth of grass and trees, they absorb water and soil, and receive the light of the sun and the moon. The change of their quality is related to the time and place.
    All kinds of physical properties are either manifested in the normal state or in changes. Knowing its nature, you can make good use of it, follow the principles of nature, and make the best use of it.
