The main components are Ca(H2PO4)2·H2O, anhydrous calcium sulfate and a small amount of phosphoric acid, containing effective (P4O10)14 20, of which 80 95 is soluble in water, which is a water-soluble fast-available phosphate fertilizer, which can be directly used as phosphate fertilizer and can also be used to make compound fertilizer. Due to the relatively low grade of calcium phosphate, the sales of unit active ingredients are high.
The phosphate fertilizer industry has seen some high-concentration phosphate fertilizers. Reaction with phosphoric acid and apatite, the resulting product does not contain calcium sulfate, but calcium dihydrogen phosphate, this product is called heavy superphosphate, is a gray-white powder, containing an effective (P4O10) up to 30 45, more than twice as much as calcium phosphate. Heavy superphosphate is mainly used as an acidic phosphate fertilizer.
The reaction of heavy superphosphate with sodium bicarbonate can release carbon dioxide gas, which is used for food fermentation.
In the coatings and plastics industry, "heavy calcium" is calcite powder, which is the abbreviation of "heavy calcium carbonate", and the main component is heavy calcium carbonate. Heavy calcium carbonate, also referred to as "heavy calcium", is usually used as a filler, widely used in artificial floor tiles, rubber, plastics, papermaking, coatings, paints, inks, cables, building supplies, food, medicine, textiles, feed, toothpaste and other daily chemical industries, as a filler to increase the volume of products, reduce production costs.
The composition of light calcium carbonate and heavy calcium carbonate is calcium carbonate, which is a common filler in coatings, plastics and other industries. The content of the primary product is 98%, and the content of the secondary product is 97

Heavy calcium has two meanings:
1. Calcite powder is the abbreviation of heavy calcium carbonate. The main components of superphosphate with the chemical formula CaCO32 and heavy superphosphate are referred to as "heavy calcium", and the chemical formula Ca(H2PO4)2 is referred to as "general calcium".

Summary. Heavy calcium and calcium hydroxide, also known as calculin, are different chemicals. Heavy calcium is a white substance with the chemical formula CaCO3, which is a carbonate.
Whereas, calcium hydroxide is a white solid with the chemical formula Ca(OH)2, which is the hydroxide of calcium. Both of them differ in terms of chemical properties, uses, etc. Heavy calcium is mainly used to solve hard water and eliminate acid-lowering, while calcium hydroxide is mainly used in water purification, oil industry and other fields.
Can you elaborate on that a little bit more?
Heavy calcium and calcium hydroxide, also known as calculin, are different chemicals. Heavy calcium is a white struggling substance with the chemical formula CaCO3, which is a carbonate. Whereas, calcium hydroxide is a white solid with the chemical formula Ca(OH)2, which is the hydroxide of calcium.
The two are different in terms of chemical properties, uses, etc. Heavy calcium is mainly used to solve hard water and eliminate acid reduction, while calcium hydroxide is mainly used in water purification, oil and land silver-based lipid industry and other fields.

The heavy calcium component is caCO3, and the calcite is directly used.
Limestone can be ground without chemical equations.
The general calcium components are Ca(old H2PO4)2·H2O and CaSO4 chemical formula is 2Ca5F(PO4)3+7H2SO4+3H2O===3Ca(H2PO4)2·H2O+7CaSO4+2HF

In the coatings and plastics industry, "heavy calcium" is calcite powder, which is the abbreviation of "heavy calcium carbonate". The composition of light calcium carbonate and heavy calcium carbonate is both calcium carbon polychic acid chemical formula: CaCO3.
In the fertilizer industry, "heavy (zhòng) superphosphate" is also referred to as "heavy differential calcium" (TSP), and the chemical formula dust is ca(H2PO4)2
Calcium hydroxide is the main component of hydrated lime, calcium oxide is the main component of quicklime, quicklime becomes mature lime when exposed to water, because calcium oxide reacts with water to form calcium hydroxide. This reaction releases a lot of heat, and adding water to quicklime can boil the water, so the lime water is naturally calcium hydroxide. >>>More
