Production Process of CS ~SiAlON & Si3N4~

Si3N4

What is Si3N4?

Si3N4 is ceramic with high strength in high temperature, good thermal shock property and good wear resistance and corrosion resistance. Si3N4 is used for automotive engine parts, tools for molten metal and bearing balls.
Si3N4 of high purity performs high thermal conductivity and is applied to thermal onductive substrates.

What are advantages of Combustion Synthesis Method to Si3N4 production?

Combustion Synthesis is a inorganic synthesis method with use of heat from chemical reaction, that means external heating energy is not necessary. And it takes very short time for synthesis.
