Good Quality Boric Acid - Samarium – WMC

Indium, soft, silvery-white, and light blue luster rare, malleable and ductile metal, is soluble easily in hot concentrated inorganic acid, acetic acid and oxalic acid, and react with the oxygen in the air slowly to form thin layer of oxidation film.

High purity indium bar, ingot, button of 99.999%, 99.9999% and 99.99999% purity 5N 6N 7N by vacuum refining and crystal pulling purification is primarily used in the manufacturing of III-V compound semiconductors, Indium Antimonide InSb, Indium Phosphide InP, Indium Nitride InN, high purity alloys, ITO powder and target, electronic paste, transistor base and as the dopant of germanium and silicon mono-crystal etc. It can be delivered in bottle with argon protection and vacuum aluminum composite bag outside package. High Purity Indium at Western Minmetals (SC) Corporation with purity 99.999% 99.9999%, 99.99999% 5N 6N 7N purity is in size of granule, lump, chunk, ingot, bar and crystal or customized specification can be delivered, which is packed in composite aluminum bag with argon gas filled protection, carton box outside.

Meanwhile, the demand for indium metal 99.99% 4N, 99.995% 4N5 has risen dramatically for liquid crystal displays, flat panel and plasma displays, and touch screens, low melting point metal alloys, LED light, photovoltaic field, wet glass production and as a coating for bearings or other parts etc. Indium wire is widely used to create high vacuum seals in cryogenic apparatus and for special lead-free indium solders. Indium Shot/ball, in 1-5mm diameter approx, tear drop shaped, can be used to prepare melts for casting, extrusion or doping, is also for plating, thermal evaporation coating for its high surface area as compared to ingot. Indium Foil is available in many sizes in sheet form, it is to be a choice for thermal interface material with some cool characteristics, and also ideal for creating cryogenic vacuum seals, and used in nuclear reactors to help control the nuclear fission reaction by absorbing some of the neutrons.
