High purity solar grade silicon nitride powder:
1. For polycrystalline and monocrystalline quartz crucible release agent. Prevent the inner wall of the crucible with molten silicon bonding, easy mold release, also play a role in the barrier layer, to ensure the purity of the silicon material.Solar grade silicon nitride powder for use as a release agent, spray the inner surface of the polycrystalline silicon ingot of the crucible is necessary for the production of polycrystalline silicon ingot product.
We choose high-purity raw material, through a variety of purification methods to produce photovoltaic grade silicon nitride powder of high purity, narrow particle size distribution, ingot mold success rate, product quality has been a number of domestic widely recognized outside of the well-known manufacturers.
