Scheelite Structure - an overview ScienceDirect Topics
Moreover, a reversible transition between the monoclinic scheelite to the tetragonal scheelite structures occurs at the temperature of 255 C. Among these three crystal structures of BiVO 4 , the monoclinic scheelite structure is the most commonly used for photo alysis because of its higher activity than the other structures 49 .

Metastable tetragonal phase CdWO4 nanoparticles synthesized with a solvothermal method - ScienceDirect
Reversible scheelite–wolframite phase changes have been reported for other tungstates , at very high pressures, much higher than achieved in this solvothermal synthesis. The material reported here is metastable, and stable indefinitely at ambient temperature and pressure.
Studies on the recovery of tungsten from a composite wolframite–scheelite concentrate - ScienceDirect
Cassiterite, wolframite and scheelite are the main valuable minerals in this ore. However, a significant amount of wolframite occurs finely disseminated in scheelite. This composite nature of mineralisation has limited the scope of using physical separation methods in generating individual concentrates of either wolframite or scheelite with economical recovery.

Pressure-induced zircon-type to scheelite-type phase transitions in YbPO4 and LuPO4 Semantic Scholar
A reversible phase transition from the zircon structure-type to the scheelite structure-type was found at ∼22 GPa for YbPO 4 and 19 GPa for LuPO 4 . Coinciding with the transition from the zircon structure-type to the scheelite structure-type, there is a ∼10% reduction in volume and a significant increase in the bulk modulus for both compounds.
