MOLYBDENUM BORIDE Usage And Synthesis

Chemical Properties

tetr; refractory material; one of several borides, other formulas: MoB, MoB2, Mo2B2, Mo2B5; used in brazes to join molybdenum and tungsten and tantalum for electronic and corrosion protection applications, and as sputtering material with 99.5% purity to produce wear-resistant and semiconductive films [KIR78] [HAW93] [CER91]

Uses

Molybdenum boride (Mo2B) is used to braze (weld) special metals and for noncorrosive electrical connectors and switches. It is also used to manufacture high-speed cutting tools and noncorrosive, abrasion-resistant parts for machinery.
