产品详细说明:

Product Name:Silicon nitride alphaPurity:>99.99%

[Cu, Cr, Co, Na, W, Fe, Zn, Mg, V]<0.0001

[Al, Ni]:0.0002

SSA:20m²/gCrystal Form:alphaColor:WhiteAPS:0.5um-1umHazard class:NoneBecause of the anti high temperature property, silicon nitride can be used as release agent successfully. It can prevent the adhibitting of melting silicon and crucible and also can obstruct the silicon and crucible so that guarantee the purity of silicon. We can control the granularity under the condition of different needs.
