Potential curves and bond strength of CP, BeO and MgO, A prioritisation hierarchy means that data is taken from harmonised C&L data and regulatory lists first, then REACH registrations and finally from CLP notifications. Beryllium Oxide is a white colored, crystalline, inorganic compound that emits toxic fumes of beryllium oxides upon heating. computers, cameras, lamps, refrigerators, washing machines) and electrical batteries and accumulators. The Support section provides tools and practical guidance to companies which have responsibilities under the EU chemicals legislation. Phys. Release to the environment of this substance can occur from industrial use: in the production of articles and industrial abrasion processing with low release rate (e.g. Beryllium oxide. cutting of textile, cutting, machining or grinding of metal). Beryllium is a specialty high temperature fluxing oxide available as a pure material in a wide variety of sizes and shapes. The source of the information is mentioned in the introductory sentence of the hazard statements. in case of consumer and professional uses). Beryllium fluoride, BeF 2, is a colorless crystalline IV.
