AR
Brown Fused Aluminum Oxide
AR is a brown fused aluminum oxide obtained from the fusion of high purity bauxites in electric arc furnaces. It presents an excellent cost/benefit relation, being recommended for refractory applications where iron content is not an issue. AR splits coarser than 2 mm are not recommend for refractories used at temperatures higher than 1300ºC.
