Advantages of silicon nitride ceramics

Silicon nitride ceramic is a super hard substance and an insulating material. It has lubricity, wear resistance, strong corrosion resistance, and oxidation resistance at high temperature. It can also resist thermal shock. According to the experimental results: silicon nitride ceramics are heated to above 1,000 ℃ in the air, and then rapidly cooled and then heated rapidly, and they will not break. It can be seen that silicon nitride ceramics have high strength, wear resistance, oxidation resistance and corrosion resistance. Silicon nitride ceramics have low density and light weight characteristics.
