Introduction
Calcined Alumina is made from low sodium calcined alumina fine powder through grinding and deep processing.
Application
Typical Applications include spark plugs, tap washers, pump seals, electronic substrates , grinding media, abrasion resistant tiles, cutting tools, bioceramics (hip joints), body armor, laboratory ware, wear parts for the textile and paper industries, and more!
Properties
Higher melting points, Excellent mechanical strength and hardness. High resistivity and Thermal conductivity.
