Abstract: A refractory shape having high density, low porosity, and small median pore size is formed from very fine grain refractory material, specifically finely milled periclase and chrome ore, by tempering the fine materials with a chemical bonding solution, specifically magnesium chloride and/or magnesium sulfate, combining the tempered fine material into larger size agglomerated pieces, drying and crushing the agglomerated pieces, grade sizing the crushed agglomerated pieces into fractions of varying size gradation, compounding a mix suitable for forming a shape by mixing the fractions in proper proportions, moistening the mix, and pressing it into the desired refractory shape. The refractory shape is then dried and fired to form a ceramic bond.
