As an excellent high-temperature engineering material, Si3N4 ceramic material can best exert its advantages in its application in the field of high temperature. Si3N4 ceramics are extremely resistant to high temperatures, and their strength can be maintained up to 1200°C without falling. They will not melt into a melt after being heated, and will not decompose until 1900°C. They have amazing chemical resistance and can withstand almost all inorganic Acid and caustic soda solutions below 30% can also resist many organic acids; at the same time, it is a high-performance electrical insulation material.
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.
Performance parameters of silicon nitride ceramics:
Room temperature flexural strength: 800-900Mpa.
Room temperature fracture toughness: 6.0-7.0Mpa.m1/2
Bulk density: 3.20-3.25g/cm3
Room temperature volume resistivity: 1014Ω.cm
Relative electric constant at room temperature: 6-7MHZ.
Thermal conductivity: 20-25W. (M.K)-1
Thermal expansion coefficient: 3.1×10-6/℃
Hardness: HRA 92-94
