Sell Selenium Dioxide

Description

Name : Selenium Dioxide Chemical Composition : SeO2 Red-white or shiny needle crystal powder, irritating smell Molecular weight: **0.*6 Vapor pressure 0.*3kPa (**7 c) Melting point: **0 ~ **0 c Solubility: Insoluble in water, ethanol, acetone, benzene, acetic acid Density: Relative density (water = 1) 3.*5 Stability: Stable Properties: White, glittering squared crystal, specific weight is ***3.*5S , is extremely apt for evaporation; sublimation temperature is **5 S , the melting point is ******0. It would easily turns into selenious acid when soluble in water(H2SeO3). The gasous selenium dioxide is yellowrish green, with stink of garlic, and toxic. The selenium dioxide is a strong oxidizer, and can be reduced into elementary selenium by sulfur dioxide, hydrogen, ammonia, carbon monoxide and carbon. Applications: used as oxidizer, catalyst, and chemical reagent, as well as be used as addictives for electrolytic manganese enterprises .
