Aluminium oxide - fused and calcined? - ATM, Optics and

May 24, 2006· Calcined means it was heated and held just below the melting point to eek out any moisture, carbon, or any other compounds you don''t want in there, it eventually reduces and oxidizes even further, thus a virtually pure Aluminum Oxide is the result. Alumina contains various impurities by design.. Like Emery and/or gem stone materials.

White Fused Alumina > Products

White Fused Alumina (WFA) is obtained from the fusion of high purity calcined alumina in electric arc furnaces. WFA is raw material characterized with high hardness, yet friable with high purity, chemical stability, a high melting point, and large crystal size.

Calcined Aluminum Oxide | Alumina | Manufacturer

Calcined alumina grains are normally composed of single platey crystals, whereas fused aluminum oxide grains tend to be fractions of large crystals and blocky in shape. A calcined crystal is theoretically a six-sided disk with a thickness of about one-fifth of its diameter. Customized sizes, vehicles, and compounds are readily available.
