White Fused alumina is produced by fusing calcined alumina in an electric arc furnace. This white fused alumina lumps is then crushed and graded to produce WFA grains and fines for abrasives and refractories.
WFA is used extensively used in vitrified abrasives in critical areas where Iron free grinding is required.
In refractories WFA is used in high alumina bricks, castables and continuous casting refractories.
