Product Description

product description
superphosphate
The main components are calcium dihydrogen phosphate Ca(H2PO4)2 and gypsum CaSO4·2H2O. Also known as superphosphate lime. It is a gray powder at room temperature. It is obtained by decomposing apatite Ca5(PO4)3F with sulfuric acid, which is called common calcium phosphate, or common calcium for short. The main components are Ca(H2PO4)2·H2O, anhydrous calcium sulfate and a small amount of . Contains effective P4O10 14% ~ 20%, of which 80% ~ 95% is soluble in water. It is a water-soluble quick-acting phosphate fertilizer, which can be directly used as phosphate fertilizer or compound fertilizer. Due to the relatively low grade of common calcium phosphate and the high sales price per unit of active ingredients, some high-concentration phosphate fertilizers have appeared in the phosphate fertilizer industry. With  and apatite reaction, the resulting product does not contain calcium sulfate, but calcium dihydrogen phosphate. This product is called double superphosphate, which is a gray-white powder with effective P4O10 as high as 30% to 45%. more than twice that of superphosphate. SSP is mainly used as an acid phosphate fertilizer. The action of superphosphate and sodium bicarbonate can release carbon dioxide gas for food fermentation. Superphosphate is a mixture.
Appearance: dark gray, gray-white, loose material. Water-soluble quick-acting phosphate fertilizer, weak acid.
