Physicochemical properties of Calcium Metaphosphate CaO6P
Calcium Metaphosphate CaO6P density 2.82}rlcm3 melting point 9}a } }so}:. There are two kinds of glass and crystalline.
Calcium Metaphosphate CaO6P glass-like pure product is a colorless and transparent polymer [Ca(P03)2] two. Slightly hygroscopic in the air. It can be dissolved and hydrolyzed very slowly in water, but can be quickly decomposed into calcium dihydrogen phosphate in the presence of acid or water vapor. The industrial product is light green, total phosphorus 64%-570IoY}OS,}J soluble phosphorus 52%-6fi% PROS, a high-concentration soluble phosphorus fertilizer.
Calcium Metaphosphate CaO6P is white in crystalline form, insoluble in water, and insoluble in citric acid solution. It cannot be used as a fertilizer, and other uses have not been found. It is prepared by burning phosphorus into phosphorus pentoxide in the air, and then 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, forages, cereals, and wheat is equivalent to or slightly higher than that of superphosphate with the same amount of phosphorus.
