Molecular Formula | AlH2P3O10·2H2O |
Physical and Chemical Properties | Properties orthorhombic crystal system crystallization, relative density 2.31. Slightly soluble in alcohol. When placed in the air for a long time, it will be partially hydrolyzed. It is relatively stable to acid. |
use | used as catalyst, pollution-free white pigment, water glass hardener, adsorption deodorant. |
production method | alumina method mixes α-alumina and phosphoric acid in molar ratio R = 0.5~0.2. Dehydrated by heating with micro-fire to generate the first product. The product is heated in an electric furnace at 300~350 ℃ in an atmosphere with high water vapor pressure to carry out polymerization reaction to generate aluminum dihydrogen tripolyphosphate. Cooling to produce finished aluminum tripolyphosphate. Its A12O3 6H3PO4 → 2AlH2P3O10 7H2O |
