Solid acid catalytic materials have attracted more and more attention because of their unique structure. Niobium tungstate, as a typical solid acid catalytic material, exhibits good catalytic activity, selectivity and stability in some organic synthesis reactions. In addition, due to its unique structure and physicochemical properties, niobium tungstate compounds have attracted widespread interest in piezoelectric, dielectric and thermodynamic aspects.

Manganese tungstate (MnWO₄) crystal has tungsten-manganese iron structure and belongs to the direct bandgap semiconductor material. Because of its special optical, electrical and magnetic properties, it has been widely used in the fields of photoluminescence, optical fibers, scintillators, humidity sensors, magnetic materials and ferroelectric materials.

In recent years, with the high integration of super LSI, the use of materials with lower resistance as electrode materials or wiring materials has been studied. In such materials, high purity tungsten with low resistance, thermal and chemical stability is used as electrode materials or wiring materials.

In recent years, lead-containing materials are being gradually eliminated due to their high pollution, high toxicity, low strength and low efficiency. High tungsten content materials are ideal substitutes at present. However, for metal materials, its processing difficulty is very high, which limits its application in some fields.
