Product Overview

 

Silicon nitride ceramic is a super hard substance, which has lubricity and wear resistance; it has strong corrosion resistance and oxidation resistance at high temperature. And it can resist the impact of cold and heat. It can be heated to more than 1 000 ℃ in the air, and it will not be broken if it is suddenly cooled and then heated sharply. It is precisely because silicon nitride ceramics have such excellent characteristics that people often use it to manufacture mechanical components such as bearings, gas turbine blades, mechanical seal rings, and permanent molds.
