METHOD OF PREPARING AMORPHOUS ALUMINOSILICATE FOR ULTRAMARINE |
摘要 |
FIELD: aluminosilicate production. SUBSTANCE: invention relates to aluminosilicates including alkali and alkali-earth metals appropriate as components for blends used for preparing ultramarine dye, curing agent in rubber industry, and in other applications. Perlite and diatomite are treated with alkali solution containing 50-100 g/l sodium oxide at 95-105 C and liquid to solids ratio (3-5): 1 for 1.5-3 h. Material is then treated at 75-120 C to produce suspension to which liquid phase from the first treatment and sodium aluminate solution are added to yield aluminosilicate with silicate modulus 2.34-2.5. EFFECT: extended aluminosilicate application area. 2 tblo
