Sodium molybdate with CAS 7631-95-0
Sodium molybdate, chemical Na2MoO4, is a white diamond crystal. Molybdenum trioxide can be produced by oxidation roasting of molybdenum concentrate, and sodium molybdate solution can be obtained by leaching, concentration, cooling, centrifugation and drying.

Determination of alkaloids and glycosides. The content of total and effective phosphorus of calcium superphosphate was determined. The serum protein and serum protein were tested. Corrosion inhibitors. H medium, T medium, modified nixu medium, MS medium and RM medium were prepared in haploid breeding. Make paint.
Molybdenum concentrate (the main group is divided into MoS2) is oxidized and roasting to produce molybdenum trioxide, which is then soaked with alkaline solution to obtain sodium molybdate solution. Sodium molybdate can be obtained by cooling and crystallizing the concentrate, centrifugal separation and drying.
