Information

Calcium Metaphosphate CaO6P Density 2.82}rlcm3 Melting Point 9}a } }so}:. There are two kinds of glass and crystal.

glassy

Calcium Metaphosphate CaO6P glassy pure product is a colorless and transparent polymer [Ca(P03)2] II. It is slightly hygroscopic in the air. It can be dissolved and hydrolyzed very slowly in water, but it can be rapidly decomposed into calcium dihydrogen phosphate in the presence of acid or water vapor. Industrial products are light green, total phosphorus 64%-570IoY}OS,}J soluble phosphorus 52%-6fi % PROS, a high-concentration conformation-soluble phosphate fertilizer.

Crystalline

Calcium Metaphosphate CaO6P is white in crystalline form, insoluble in water and hardly soluble in citric acid solution and cannot be used as fertilizer, and no other uses have been found. It is produced by burning phosphorus into phosphorus pentoxide in the air, and then mixing with phosphate rock powder in the presence of high temperature and water vapor. Can be used as base fertilizer. The yield-increasing effect on legumes, pastures, grains, and wheat is equivalent to or slightly higher than that of superphosphate with the same amount of phosphorus.
