Abstract
An aluminothermic reduction reaction mixture consisting essentially of an admixture of manganese dioxide (MnO.sub.2) and metallic aluminum (Al) with alumina (Al.sub.2 O.sub.3) added thereto. The reaction does not yield a metallic phase, but produces a single phase comprising a galaxite containing slag.
Claims6
An aluminothermic reduction reaction mixture, which produces only a slag phase, consisting essentially of a particulate admixture of metallic aluminum, manganese dioxide and alumina having an aluminum to manganese dioxide ratio of approximately 0.21 and an alumina content of from 15 to 30 weight percent.
An aluminothermic reduction reaction mixture consisting essentially of a particulate admixture of about 63 wt. % manganese dioxide, 14 wt. % aluminum, and 23 wt. % alumina.
