Specifications
Features:
Primary crystal has good sphericity. It can be easily sintered. It also has characters of fine grain size, high purity, good grindability, narrow particle size distribution, good dispersion and high porcelain density. Our company developed this kind of powder for electronic substrate tape casting. For example d23:96 porcelain, its porcelain density can reach to over 3.75g/cm3 and shrinkage rate is only 14.5~15%.
