Ready To Press （RTP）Alumina For Alumina Ceramics
Applications
Specification
Overview:
Select high-purity, suitable particle size alumina, and use pressure or centrifugal spray granulation. The powder particles have good gradation, good fluidity, high strength, not easy to break, and stable shrinkage. Porcelain forming temperature is low and density is high. Suitable for dry pressing, rapid stamping, isostatic pressing and other processes. It can be used to produce more than 99% alumina ceramics.
