Good Thermal Shock Resistant Silicon nitride ceramic strip bar

Silicon nitride ceramic strip
Is a superhard material, which has lubricity and wear resistance. It does not react with other inorganic acids
it has strong corrosion resistance and high temperature oxidation resistance.
And it can also resist cold and heat shock, heat up to more than 1000 degrees in the air, rapid cooling and then rapid heating, and will not break.

Silicon nitride ceramic strip

Silicon nitride Strip is a kind of high-strength structural ceramics with broad development prospects. Compared with other ceramic materials, silicon nitride ceramics have high properties (such as high strength, high hardness, good thermal shock resistance, high fatigue toughness, high bending strength at room temperature, wear resistance, chemical corrosion resistance, good high-temperature stability, oxidation resistance, etc.), and have a small proportion.
