Zinc tungstate is an inorganic chemical compound of zinc from the tungstate group .

Occurrence

Zinc tungstate occurs naturally in the form of mixed crystals with iron as the mineral sanmartinite .

Extraction and presentation

Zinc tungstate can be obtained by reacting sodium tungstate with zinc salt solutions such as zinc (II) chloride or zinc nitrate .

{\ displaystyle \ mathrm {Na_ {2} WO_ {4} + ZnCl_ {2} \ longrightarrow ZnWO_ {4} \ downarrow + \ 2 \ NaCl}}

properties

Zinc tungstate is a white solid that is practically insoluble in water. It has a monoclinic crystal structure of the wolframite type with the space group P 2 / c (space group no. 13) . At very high pressures above 30 GPa there is a phase change to a crystal structure of the β- fergusonite type . Template: room group / 13

use

Zinc tungstate is used as an intermediate in the manufacture of drugs and as a material for scintillators .
