Principle of reaction sintering of silicon carbide ceramics

2018-08-13 17:04:20

Just now we have listed the USES of silicon carbide ceramics for you, and many customers wonder: what is the process used to make this? It can be used in so many fields. Here is the principle of reaction sintering of silicon carbide ceramics. Reaction combined with silicon carbide is refers to the element containing silicon carbide and carbon powder, carbon and silicon in the process of reaction reaction to generate a new combination of the original with carborundum, thus forming a silicon carbide composite materials, the preparation process is as follows to silicon carbide powder and carbon powder mixed with organic binder, after forming, drying, debonding, siliconizing and made at last.

This kind of sintered silicon carbide density can reach 3.08, with good abrasion resistance, corrosion resistance, etc., which is highly demanded by the market.

Reactive sintering silicon carbide is also known as activated sintering or enhanced sintering.

More rigorous, activated sintering and enhanced sintering are different.

Activated sintering refers to the sintering method that can reduce the activation energy of sintering, enable the system to be sintered at a relatively low temperature at a relatively fast speed, and improve the properties of the sintered body.

Enhanced sintering generally refers to all sintering processes that can increase the sintering rate or enhance the properties of the sintered body (through alloying or inhibiting grain growth).
