Applications of silicon nitride include:

1. Used as mold release agent for polycrystalline silicon and monocrystalline silicon quartz crucible.Prevent the inner wall of crucible from bonding with fused silicon material, facilitate demolding, and play a role of barrier layer to ensure the purity of silicon material.Solar grade silicon nitride powder is used as mold release agent,and sprayed on the inner surface of polysilicon ingot crucible, it is a necessary product for polysilicon ingot production.

2. Silicon nitride is used as high grade refractory, such as si3n4-sic combined refractory, can be usedfor blast furnace body and other parts,If combined with BN as si3n4-bn material, it is used for horizontal continuous casting separation ring.

3. Silicon nitride can also be used in thin-film solar cells.Silicon nitride film plating by PECVD method can not only reduce the reflection of incident light, but also, in the deposition process of silicon nitride film, the hydrogen atom of the reaction product enters the silicon nitride film and silicon wafer, playing the role of passivation defect.

Adopting unique synthesis technology and high purity raw materials, through a variety of purification methods, the production of photovoltaic grade silicon nitride powder has high purity, narrow particle size distribution, high success rate of ingot casting, and product quality has been recognized by many customers, if you have interests in the Si3N4 powder, please send us an inquiry to get more details.
