Synthesis of zirconium silicate
Zirconium silicide is a silicate, gray cubic crystalline powder. Used as fine ceramic raw material powder, crucible for semiconductor film production.
Synthesis method of zirconium silicide:
1. Zirconium and silicon powder as raw materials. Smash metal zirconium, again with silicon powder mixed fully, put the mixture into graphite furnace, reaction, heating to 900 ~ 1000 ℃ and then pass into hydrogen, reaction temperature to 1200 ℃ or so, again made silicide zirconium.
2.Use the direct method. Zirconium silicide was prepared from zirconium metal and silica powder:
Will first zirconium metal pieces, and then mixed with silicon powder fully, put the mixture into graphite furnace, heating to 900 ~ 1000 ℃ for reaction, and then pass into hydrogen, heating up to about 1200 ℃ for homogenizing reaction, which made silicide zirconium.
