Composition and Properties of Triple Superphosphate Obtained

2021年8月17日 Triple superphosphates [TSPs, Ca(H2PO4)2H2O] were produced by exothermic reactions of oyster shells and different concentrations of phosphoric acid (10, 20, 30, 40, 50, 60, and 70% w/w) in a molar ratio of 1:2.

8.5.2 Triple Superphosphates - U.S. Environmental Protection Agency

Triple superphosphate, also known as double, treble, or concentrated superphosphate, is a fertilizer material with a phosphorus content of over 40 percent, measured as phosphorus pentoxide (P2O5). Triple superphosphate is produced

Factsheet Main Characteristics and Agronomic Performance of

PRODUCTION AND CHARACTERISTICS Triple superphosphate is a soluble phosphate fertilizer containing about 20% total P (44-48% P 2 O 5). Besides P, TSP also contains 13-15% calcium (Ca), and a maximum of 4% residual phosphoric acid (H 3 PO 4). The concept of superphosphate fertilizer production is relatively simple, involving the addition of ...

Superphosphate — Wikipédia

Le superphosphate triple (TSP) est obtenu par attaque chimique acide d'une roche phosphatée par de l'acide phosphorique. Il s’agit de la forme de superphosphate la plus efficiente. Sa teneur en P 2 O 5 est de l’ordre de 46 %.

Superphosphate - Wikipedia

Triple superphosphate is obtained by treating phosphate rock with phosphoric acid. Traditional routes for extraction of phosphate rock use sulfuric acid to produce single superphosphate, an approximate 1:1 mixture of Ca (H2PO4)2 and CaSO4.

Superphosphate - an overview ScienceDirect Topics

2012年1月10日 Triple superphosphate: Two processes have been used to produce triple superphosphate: run-of-the-pile (ROP-TSP) and granular (GTSP). GTSP yields larger, more uniform particles with improved storage and handling properties than ROP-TSP. Most GTSP material is made with the Dorr-Oliver slurry granulation process.

Superphosphate - an overview ScienceDirect Topics

2012年1月10日 This material is called ordinary superphosphate or single superphosphate and is 0-20-0-11S. Rock phosphate treated with phosphoric acid produces triple superphosphate or concentrated superphosphate with a grade of 0-46-0 with no sulfur. Almost all superphosphate produced today is triple superphosphate.
