Skin diseases caused by beryllium and its compounds

1. Industrial application Beryllium is mainly used in alloy manufacturing, X-ray tube, high temperature resistant ceramics and atomic energy industry. Smoke and dust from beryllium fluoride (BeF2), beryllium hydroxide [Be (OH) 2], beryllium sulfate (BeSO4middot; 4H2O), beryllium chloride (BeCl2), beryllium oxide (BeO), and metal beryllium often occur in beryllium smelting. And solution. Among them, beryllium oxide dust is the easiest to fly. 2. Physical and chemical properties Beryllium is an off-white light metal, which has the characteristics of light weight, strong tension, hard, high temperature resistance, stainless, not easy to be corroded, not affected by magnetic force, and not sparking when impacted. Beryllium volatiles are easily oxidized into very light beryllium oxide dust in the air. In nature, beryllium mainly exists in beryl (3BeOmiddot; A12O3middot; 6SiO2).
