Application
Silicon Carbide for Precision Ceramics
Special ceramics generally use high-purity micro-nano materials, and the raw materials used are required to be: 1. Small particle size, narrow particle size distribution range, or a certain particle size gradation. 2. The particles are equiaxed, with few agglomerated particles and low agglomeration strength. 3. The chemical purity and chemical composition uniformity can be controlled, and the particle size D50 is less than 0.8 microns, and the maximum particle size does not exceed 5 microns.
