Abstract
CaWO4 crystals were synthesized by a microemulsion method. Various sizes and shapes of CaWO4 were obtained by changing the molar ratio (w) of H2O to CTAB. At w=5 and 10, oval CaWO4 crystals with length of 100 nm and 500 nm were obtained, respectively. At w=20, rod-like CaWO4 crystal with length of 1 μm was obtained. The sphere CaWO4 crystal with length of about 2~3 μm was obtained at w=30. The CaWO4 crystal morphology changes from oval to sphere via a rod by aggregation with increasing the molar ratio of H2O to CTAB.
