High Purity and Conversion Rate Calcined Alumina Powder for Ceramic Injection Molding
1. Calcined Alumina Introduction
Calcined alumina is generally used in the manufacture of high-grade ceramic shapes, refractories and fused alumina abrasives. It can be compressed to produce a fired density of 3.8 or more. Amazingly, ceramic bodies containing 95% or more alumina are being employed to produce ceramic parts for a wide range industries (fired to 1400C or more). Fabrication methods and glazing vary according to application.
