1. Fired Silicon Nitride Ceramics
2. Releasing Agent in the Ingot Process of the Photovoltaic Industry
After years of research and production practice, we (Itowu) found that the purity of silicon nitride powder determines the performance of silicon nitride ceramic products. According to different standards and needs, different production methods are adopted to maximize the purity of silicon nitride powder products.
