Photovoltaic-grade silicon nitride powder is primarily used as a release agent tc spray on the inner surface of high purity quartz crucible. This powder plays a crucial role inthe production of polycrystal line silicon ingots.

Our photovoltaic-grade silicon nitride powder is produced using a unique process. We begin with high-purity silicon as the raw material and utilize advanced techniques, such as precise control of particle size ratios and multi-level purification technology. These methods guarantee exceptional product performance. The entire process is meticulously controlled and adaptable, yielding a powder with high purity, a narrow particle size distribution, and exceptional stability.
