For sale red phosphorus (Dnipro, Ukraine), Dnepropetrovsk region.

For sale Phosphorus red. The toxicity of ego is thousands of times less than that of white, so it is used much more widely, for example, in the production of matches (the grinding surface of the boxes is covered with a composition based on red phosphorus). The density of red phosphorus is also higher, reaching 2400 kg/m³ in cast form. When stored in the air, red phosphorus in the presence of moisture gradually oxidizes, forming a hygroscopic oxide, absorbs water and turns sour ("soaks"), forming viscous phosphoric acid; therefore, it is stored in an airtight container. When "soaking" - they are washed with water from residual phosphoric acids, dried and used as intended.
