MOLYBDENUM BORIDE Usage And Synthesis
Chemical Properties
refractory material; borides used as a braze to join molybdenum, tungsten, and tantalum, and niobium parts for electronic, corrosion, and abrasion protection, used as a sputtering target with 99.5% purity to produce films which may be wear-resistant and semiconducting [CER91] [HAW93] [KIR78]
Physical properties
Corroded by molten metals Al, Mg, V, Cr, Mn, Fe, Ni, Cu, Nb, Mo, and Ta; corrosion resistant to molten Cd, Sn, Bi, and Rb
Uses
Brazes to join molybdenum, tungsten, tanta-lum, and niobium parts, especially electronic com-ponents, corrosion and abrasion-resistant parts, cut-ting tools, refractory cermets.
Safety Profile
Poison by intratracheal route. Moderately toxic by ingestion and intraperitoneal routes. When heated to decomposition it emits toxic fumes of boron and Mo.
