Solar grade silicon nitride powder, as release agent, is used to spray to the inner surface of fused silica crucibles. It is the necessities for the production of multi-crystal ingots.
The solar grade silicon nitride powder produced by Tomley is synthesized through special nitridation process of silicon powder which ensures the powder with the character of high purity, narrow particle size distribution and increases the success rate of ingot demoulding. The products are widely used by many well-known companies at home and abroad.
Tomley attaches great importance to new product innovation and R & D work. We recently have developed the upgraded silicon nitride powder (TX-Q) with the model of TS by the innovation and the introduction of new equipment. With the improvement of purity and technical specifications, the solar grade silicon nitride powder had a 50 percent market share in China or more. Our cooperation customers are GCL, LDK, JinKo, JA, Hanwha, YingLi Solar, SORNID, TSL Solar, Hareon Solar, etc. We provide free technical support for our customers.
