Use:
Agriculture use:raw material of phosphate fertilizerand feed nutrients
Industry use: chemical raw materials
1.Protect the metal from corrosion
2.Mixed with nitric acid as chemical polishing agentto improve the surface finish of metal
3.Material of phosphatide which is used for producewashing product and insecticide
4.The production of phosphorus containing flameretardant materials.
Food additives use:acidic flavoring,Yeast Nutri-ents, ,such as coca-cola.
Medical use:to produce medicine containing phos-phorus,such as Na 2 Glycerophosphat
Following the discovery of phosphorus and German chemist Conquer to produce phosphorus, British chemist Bo Yili also independently produced phosphorus. He was also the first chemist who studied phosphorus and compounds. The thesis “A New Experiment of the Cold Light Observed” wrote “Phosphorus generates white smoke after burning, and the solution generated after the action of white smoke and water is acidic.” ), And the solution generated with water is phosphate, but he did not further study phosphate.
The earliest chemist who studied phosphate was French chemist Lawar. In 1772, he did such an experiment: Put the phosphorus in a mercury -sealed bell cover to burn it. The experimental results are concluded that a certain amount of phosphorus can be burned in an air of a capacity; white powder pieces of water -free phosphorus are generated when phosphorus burn, such as fine snow; 80%; the phosphorus is about 2.5 times before the burning; the white powder is dissolved in the water to form phosphate. Lavis also proves that phosphate can be made with concentrated nitric acid and phosphorus.
After more than 100 years, German chemist Libii has done many agricultural chemical experiments to unveil the value of phosphorus and phosphate on plant life. In 1840, Li Bixi’s “The role of organic chemistry in agriculture and physiology” scientifically demonstrated the fertility problem of soil and pointed out the role of phosphorus on plants. At the same time, he further explored the application of phosphate and phosphate as fertilizer, and the production of phosphate has entered a large -scale era.
