Prospect of nitride bonded silicon carbide

Judging from the current situation of mine operation in China, mechanical work is still the main work. Therefore, machinery is in operation for a long time, which leads to rapid wear and failure. In addition, because the residues generated after wear and tear accidentally fall into the materials, the product quality will eventually be directly affected. In order to increase the service life of mining equipment, it is necessary to further develop new wear-resistant materials, which has far-reaching significance for the development of the mining industry. The formation of ceramic materials is made of silicon nitride and silicon carbide wear-resistant materials. nitride bonded silicon carbide has excellent structure, strong strength and hardness, low coefficient of linear expansion, high temperature oxidation resistance and high temperature creep resistance. Therefore, silicon nitride and silicon carbide wear-resistant materials have been fully used in many industries. Silicon nitride and silicon carbide wear-resistant materials will be used more and more in mining machinery.

As we all know, nitride bonded silicon carbide is a kind of non oxide ceramic material in terms of performance. Compared with oxide ceramic material, it has its own unique characteristics. Silicon nitride bonded silicon carbide material has extremely high hardness and creep resistance. Even under high temperature environment, these properties will not be affected. It can be said that its unique advantages are irreplaceable by other materials. nitride bonded silicon carbide itself belongs to mechanical bonding, that is, needle shaped or fibrous Si3N4 wraps fine SiC and then fuses with silicon carbide. From the current situation, silicon nitride bonded silicon carbide material is an indispensable refractory material in ceramic kilns, which is more fully used. Nitride bonded silicon carbide material gradually replaces clay bonded silicon carbide material. In addition, because the performance price ratio of silicon nitride bonded silicon carbide material is not high, compared with recrystallized or recrystallized silicon carbide, Silicon nitride bonded silicon carbide materials have more development prospects in the market.
