Zirocnia Ceramics:
Precision ceramics, also known as high-performance ceramics, can be divided into carbides, nitrides, oxides and borides. They can be subdivided into structural ceramics, cutting ceramics and functional ceramics (mainly using their electricity). , magnetic properties) three categories. Silicon Nitride has crystal and amorphous, said amorphous silicon nitride is amorphous silicon nitride, and crystalline silicon nitride mainly has early tetragonal silicon nitride (lattice constant a=9.245, c =8.48), common hexagonal zirconia (there are two crystal forms, namely needle-like crystal α-Si 3N 4 and granular crystal β-Si 3N 4 ), cubic silicon nitride. Ceramics have excellent heat resistance, hardness, abrasion resistance, corrosion resistance, and lightness, which are not found in Other Materials such as metals, but ceramics also have brittleness, impact resistance, and low thermal shock resistance. Inherent shortcomings, the use of functions is greatly limited
It is extremely resistant to high temperatures and its strength can be maintained to a high temperature of 1200 ° C without falling. It does not melt into a melt after being heated, and will not decompose until 1900 ° C.
Since silicon nitride is a covalent compound with high bond strength and can form an oxide protective film in air, it also has good chemical stability. It is not oxidized below 1200 °C, and a protective film is formed at 1200 to 1600 °C to prevent further. Oxidation.
