Alumina Hydrate MALHY 1 KgAlumina Hydrate MALHY Al(OH)3 Hydrated alumina is a fine granular white powder that is typically added to glazes as a source of alumina. Typical analysis: Al(OH)3 99. 5% pure Melting point 3000C The hydrated version of alumina remains in suspension better in glaze slurries, and has better adhesive qualities than Calcined Alumina Oxide. Small additions of alumina hydrate to a glaze can also enhance the color of Cr Al pinks. Larger additions can impart
