Sodium molybdate (Na2MoO4) dihydrate Use and Manufacturing

Methods of Manufacturing

Liquid alkali extraction method molybdenum concentrate is oxidized and roasted to produce molybdenum trioxide, and then leached with liquid alkali to obtain sodium molybdate solution. The leaching solution is filtered by suction, evaporated and concentrated. The concentrated solution is crystallized by cooling and centrifuged at 70~80℃ Dry at temperature to obtain finished sodium molybdate. Its 2Mos2+7O2→2MoO3+4SO2↑MoO3+2NaOH+H2O→Na2MoO4?2H2O

Uses

manufacture of inorganic and organic pigments, corrosion inhibitor, bath additive for metals finishing, reagent for alkaloids, micronutrient for plants and animals.
