Rock phosphate is made to react with concentrated sulphuric acid which produces a mixture of calcium sulphate and calcium-di-hydrogen phosphate. This is super phosphate.
Equation Ca3(PO4)2+2H2SO4 => 2CaSO4+Ca(H2PO4)2
They have not released it, it's a secret.
Superphosphate of lime is a fertilizer containing a high concentration of phosphorus in the form of water-soluble phosphate. It is typically produced by treating phosphate rock with sulfuric acid to create a mixture of phosphoric acid and calcium sulfate. This mixture is then further processed to form the final product known as superphosphate of lime.
The chemical formula of potassium superoxide is KO2.
When superphosphate and urea are blended together, the urea hydrolyzes to form ammonium ions, which react with the phosphates in the superphosphate to form ammonium phosphate. The resulting blend contains ammonium phosphate, which provides both nitrogen and phosphorus for plant growth.
The main feeds (ingredients) for the process are concentrated sulphuric acid, and phosphate rock. Phosphate rock is a mixture of many minerals, but it has generous amounts of "insoluble" phosphate (PO4). Plants cannot absorb this PO4 so it is useless as a fertiliser. The main aim of the super phosphate process is to convert this PO4 into a "soluble" form.The phosphate rock is crushed into fine particles,The rock is reacted with concentrated sulphuric acid, converting much of the PO4 into a soluble form. Most of this reaction occurs quickly, but it will continue slowly over the next few days,The reacted mixture is granulated (turned into small pellets) and the granules are left to mature for weeks before use.
SSP= Single Super Phosphate is a type of Fertilizer used for agriculture. Molecular formula:Ca(H20P4)2.H2O 4,
Triple super phosphate is generally more effective, as it has higher phosphorous (P) levels. However if you need to raise the level of sulphur (S) in your soil you may be better off with normal super, as it has higher S levels. Also, keep in mind that triple super is usually more expensive.
Super phosphate is calcium dihydrogen phosphate. It can be prepared by reacting sulfuric acid with calcium phosphate :Calcium phosphate + Sulfuric acid ----> Calcium sulfate + Calcium dihydrogen phosphate3 Ca3(PO4)2 + 6 H2SO4 ----> 6 CaSO4 + 3 Ca(H2PO4)2
super phosphate is a dangerous adulterant
Fresh super is quite a dark grey colour. However by the time it's ready for farm use it should be an almost white colour.
No. It doesn't contain any nitrogen. It contains 8.8% phosphorus (P) and 11 % sulfur (S) as sulfate.

It is just the name for the fertiliser containing phosphorous and coated by a sulphur prill.

Single superphosphate is made by reacting phosphate rock with sulfuric acid to produce phosphoric acid. This phosphoric acid is then mixed with phosphate fertilizer to produce single superphosphate. The mixture is granulated and dried before being ready for use as a fertilizer.
Superphosphate of lime is a fertilizer containing a high concentration of phosphorus in the form of water-soluble phosphate. It is typically produced by treating phosphate rock with sulfuric acid to create a mixture of phosphoric acid and calcium sulfate. This mixture is then further processed to form the final product known as superphosphate of lime.
single super phosphate or superphosphate of lime, Ca(H 2 PO 4 ) 2 , is a compound produced by treating rock phosphate with sulfuric acid or phosphoric acid, or a mixture of the two. It is the principal carrier of phosphate, the form of phosphorus usable by plants, and is one of the world's most important fertilizers. Ordinary superphosphate contains about 20% available phosphate; double superphosphate (also called treble superphosphate) contains 40%-50% available phosphate.
