Fused Mullite and Fused Zirconia Mullite are produced from high purity raw materials in electric arc furnaces. The molten material undergoes cooling, crushing, grinding, sieving, classifying, and, of course, various quality checks.

Fused Spinel grains are produced from high purity raw materials in electric arc furnaces to obtain maximum amount of spinel crystals. The molten material undergoes cooling, crushing, grinding, sieving, classifying, and, of course, various quality checks. Fused Spinel is offered in varying percentages of MgO to provide an Alumina-Rich Spinel, a Stoichiometric Spinel (or very close), and a Magnesia-Rich Spinel.

Sintered Spinel is an alumina and magnesia composite and is produced in different ratios of alumina and magnesia. The high quality of the products is ensured by using high purity raw materials with detailed control of the production process. During sintering, aplhpa-alumina crystals are combined with magnesia crystals to form larger crystals which give spinel a unified crystal structure, low porosity, and high density.
