Silicon Nitride Ceramic:

The concept of ceramics has developed into a sintered body that can be obtained by three-dimensional bonding of materials through molding and high-temperature sintering. (This concept also includes glass in the scope of ceramics)
The theory of studying the structure and properties of ceramics has also been developed: ceramic materials, the influence of internal microstructures (microcrystalline crystal surface effect, porous multiphase distribution) on mechanical properties has been developed. The relationship between the properties of materials (optical, electrical, thermal, and magnetic) and the forming, as well as the particle size distribution, and the relationship between the adhesive interface have also been developed. Ceramics should become a form of material that carries certain properties. This should be related to quantum mechanics, nanotechnology, surface chemistry and other disciplines. The subject of ceramics has become a comprehensive subject. This development is to some extent related to polymer molding. They should influence each other. The titanium diboride powder is gray or gray-black and has a hexagonal (AlB2) crystal structure. Its melting point is 2980°C and it has high hardness. The anti-oxidation temperature of titanium diboride in the air can reach 1000℃, and it is stable in HCl and HF acid. Titanium diboride is mainly used to prepare composite ceramic products. Because of its resistance to molten metal corrosion, it can be used in the manufacture of molten metal crucibles and electrolytic cell electrodes. Titanium boride (TiB2) is the most stable compound of boron and titanium. It has a C32 structure and is combined in the form of valence bonds. It is a metalloid compound of the hexagonal crystal system. The structural parameters of the complete crystal are: a is 0.3028nm and C is 0.3228nm. In the crystal structure, the boron atom plane and the titanium atom plane alternately form a two-dimensional network structure, in which the B and the other 3 B are covalently bonded, and the extra electron forms a large π bond. This graphite-like layered structure of boron atoms and Ti outer layer electrons determine that TiB2 has good conductivity and metallic luster, and the Ti-B bond between the boron atomic surface and the titanium atomic surface determines the high hardness of this material And brittleness.
