Massive Selection for Yttrium Oxide 4n5 - Tellurium Oxide – WMC

Boron, a very hard, lubricant black or brown material with a high melting point of above 2300°C, is not soluble in water but dissolved in boiling nitric acid, sulfuric acid and most of the molten metals such as copper, iron, manganese, aluminum and calcium etc. Boron has chemical reaction with fluoride at room temperature but not affected by hydrochloric acid and hydrofluoric acid in aqueous solution.

High pure halogenated boron, brownish color, 99.99%, 99.999% and 99.9999% 4N 5N 6N by bromated synthesizing reduction method can be used for the production of a variety of boron compounds, and as additive in special alloy production. Furthermore, it finds more application in Ultrahigh Speed Integrated Circuit, medicine, ceramics, for high temperature resistant alloy, catalyst, and used as a neutron absorber in nuclear chemical industry.High Purity Boron at Western Minmetals (SC) Corporation with purity 99.99% 99.999%, 99.9999% 4N 5N 6N purity is in size of powder, granule, lump or customized specification can be delivered, which is packed in composite aluminum bag with argon gas filled protection, carton box outside.
