What is Phosphorus ?

With the progress of science and technology and the development of society, chemical products have invariably permeated our daily lives, in medicine, food, cosmetics, electronics, industry, and other areas, becoming an essential part of our lives. One such product is Phosphorus which has developed particularly rapidly in recent years. Do you know about Phosphorus ?

The official answer: Red phosphorus (Red phosphorus [5]), also known as red phosphorus, is a purple-red amorphous powder, shiny and non-toxic. Under high pressure, it is heated to 590 ° C and begins to melt, if it is not pressurized, it does not melt and sublimate, and after vaporization, it condenses to get white phosphorus. Red phosphorus forms a polymeric structure of chains or rings with the single bond of P4 tetrahedron, has high stability, is insoluble in water, carbon disulfide, is soluble in anhydrous ethanol, and is soluble in alkali. It reacts with nitric acid to form phosphoric acid, which is heated in chlorine to form chloride. Yellow phosphorus is heated to 250 ° C for several days under atmospheric pressure in vacuum, and converted to red phosphorus. Red phosphorus can be used in the semiconductor industry as a diffusion source, organic synthesis and matchmaking, as well as as as insecticides, rodenticides, fireworks and smoke screen bombs.

What’s the application of Phosphorus ?

Red phosphorus can be used in the preparation of semiconductor compounds and as an dopant for semiconductor materials. It can be used for flame retardant polycarbons, polystyrene, polyester, nylon, polycarbonate, polyoxymethylene, epoxy resin, unsaturated resin, rubber, textiles, etc. Flame retardants of oxygen-containing polymers such as polyethylene terephthalate, polycarbonate and phenolic resin are particularly effective. Compared with other phosphorus-based flame retardants, red phosphorus of the same quality can produce more phosphoric acid, which can cover the surface of the flame retardant material, and speed up dehydration and carbonization on the surface of the material, forming a liquid film and carbon layer that can isolate the external oxygen, volatile combustibles and heat from the internal polymer matrix and interrupt combustion. Because the amount of red phosphorus is small when it meets the same flame retardant requirements, and the melting point of red phosphorus is high and the solubility is poor, some of the physical properties of polymers with red phosphorus flame retardant are better than those of similar polymers prepared with general flame retardants. The combination of red phosphorus and halogenated flame retardants can improve flame retardant efficiency. Red phosphorus can also be used to make matches, fireworks, as well as aluminum phosphide, phosphorus pentoxide, phosphorus trichloride and so on. It is a raw material for the production of organophosphorus pesticides. The metallurgical industry is used to manufacture phosphor bronze sheets. It is also used for deacidification of light metals and pharmaceuticals. For organic synthesis.

WHY THEY SAY TO US

United Kingdom Giles
United Kingdom Giles
Peter has been my partner for many years, we met at the Shanghai CPHI Fair in 2014, for the first time I didn't have much interest in Peter's products because our company had a stable supplier. Although we didn't work together, Peter would often send me important news and interesting trend information about the industry, so we became good friends, even though I didn't place any orders with him during this time, even if it was a sample order. In September 2016, our original supplier was unable to provide us with the quality and delivery guarantees we needed, so I first thought of Peter and his company. Until now, we have maintained a very good personal friendship in addition to a steady business relationship.

In all my years of sourcing from China, I first time to found that working with Sincere Chemical was so good, they helped me with all the production and delivery as well as a lot of technical expertise, which saved me a lot of time. When I first approached Peter for a quotation for Optical Brightener, he made me a detailed quotation with not only prices but also foreign trade details, company profile, company strengths, R&D capabilities, production capacity, packaging methods, raw material control, environmental protection, and much more. This information was a very important reference for me in making purchasing decisions. Sincere Chemical is a trustworthy supplier and I believe our business will grow from strength to strength!

Hi, I'm Kim, I'm Peter's partner and although I don't like him very much (because he never gives me more money for my prices, hahaha) I'm still willing to write him customer feedback. As an international buyer, I have to deal with a lot of things every day and my inbox is often full of development letters. It's a lot of junk and meaningless pleasantries, which I don't like that much, but Peter's emails always give me a better understanding of the product and the industry. I am also very pleased with his work ethic, and I am very happy with his work every time I work with him, not only in providing quotations but also in facilitating all the details of my work so that I can concentrate more on other things, so he is the best supplier for me. Although his prices are not the lowest among all suppliers, his products give me the greatest peace of mind.
