Influence of raw materials morphology on properties of magnesia-spinel refractories

摘要: Abstract The work concerns magnesia-spinel refractories (MSp) used in cement industry. These materials replace magnesia chromite due to environment protection. paper summarizes results of investigation on influence raw final properties products. In experiments sintered or fused magnesia, and spinel were used. Clinkers differ chemical composition morphology. Grain mixtures was calculated the basis modified Andreasen curve according Dinger Funk's model. Essential clinker morphology established. Porosity pore size distribution determine their strength gas permeability. Relations between these parameters allow controlling products a wide range.
