General description

Sodium molybdate dihydrate (SMD) is a molybdic acid disodium salt. It crystallizes in the orthorhombic space group, Pbca. The toxic effect of SMD on the avian species, northern bobwhite quail has been investigated. Its ability to inhibit corrosion of 6082 wrought aluminum alloy has been studied in NaCl solution of chlorosulfonic acid.

Application

Sodium molybdate dihydrate has been used as one of the phosphatase inhibitor during the Western blot analysis.
It may be used to prepare:
  • Shuttle-like barium molybdate (BaMoO4) microstructures under microwave conditions.
  • Nickel-molybdenum-zinc (NiMoZn) electrode.
  • Eu3+ doped lead molybdate (PbMoO4) nanocrystals (NCs) under microwave conditions.
