CompoundsMost silicon is used industrially without purification and, in fact, is usually relatively little processed from its native form. More than 90 percent of the Earth's crust is made up of silicate minerals, which are compounds of silicon and oxygen that often carry metal ions while negatively
READ MOREVacuum induction melting (VIM) uses an electric current to melt metal in a vacuum. The first prototype was developed in 1920. [1] Induction heating induces eddy currents in the conductor. The eddy currents create a thermal effect to melt the metal. [2] Vacuum induction melting has been used in the a
READ MOREVacuum arc remeltingVacuum arc remelting (VAR) is a secondary melting process used to produce metal ingots with increased chemical and mechanical homogeneity for demanding applications. [1] The VAR process has revolutionized specialized traditional metallurgical technology indust
