Fused Alumina Refractory Block from Mexico
Fused alumina refractory blocks are dense blocks made from fused alumina with over 90% Al2O3 content, fired and shaped for use in blast furnace hearths. They provide superior abrasion resistance and are used in heavy industrial construction for high-wear zones, qualifying as refractory ceramic constructional goods.
