Sodium Metaphosphate, Insoluble, occurs as a white, crystalline powder. It is a high-molecular-weight sodium polyphosphate composed of two long metaphosphate chains (NaPO3) that spiral in opposite directions about a common axis. The Na2O/P2O5 ratio is about 1.0. It is practically insoluble in water but dissolves in mineral acids and in solutions of potassium and ammonium (but not sodium) chlorides. The pH of a 1:3 slurry in water is about 6.5.
Ammonium Metaphosphate is white powder or granular, odourless, tasteless, insoluble in water.
Calcium Metaphosphate is white crystal, insoluble in water, hardly soluble in citric acid solution.
Magnesium Metaphosphate is white glassy powder, slightly soluble in water, acid and alkali.
Aluminium Dihydrogen Phosphate is white powder, easily soluble in water. Curing at room temperature. It has high temperature resistance, vibration resistance, spalling resistance capacity. With good red line absorption capacity and insulation.
Boron Phosphate crystallizes in tetragon. Slightly soluble in water, hydrolyzing in water. Solution is strong acidity, slightly hygroscopic.
