“…In this case, particles have a growth form, which is often different from the equilibrium form. Typical examples are Bi 2 WO 6 obtained from Bi 2 O 3 and WO 3 using Li 2 SO 4 -Na 2 SO 4 (Kimura & Yamaguchi, 1982) and TiZrO 4 from TiO 2 and ZrO 2 using KCl (Kimura et al, 1992). The Bi 2 WO 6 and TiZrO 4 particles have rectangular and irregularly rounded shapes, whereas the equilibrium forms are an oblate an oblate sphere and needle, respectively.…”

“…Thus, columnar particles become more regular in morphology as synthesizing temperatures increases. Kimura et al . showed that the molten salt synthesis of powders includes two processes: the particle nucleation and growth.…”

“…Kimura et al showed that the molten salt synthesis of powders includes two processes: the particle nucleation and growth. 17 The nucleation process depends on variable parameters such as temperature, time, and solubility of reactants in molten salt. The initial morphology of powders depends on the particle nucleation process, and it is then controlled by the growth process.…”

“…Recently, high purity oxide powders with homogeneous and controllable morphologies have been successfully prepared by MSS. [14][15][16][17][18] However, the investigation on the synthesis of single-phase forsterite powders with controllable morphologies by MSS is still sparse. Sun et al attempted to synthesize nickel-doped forsterite (Ni 2+ : Mg 2 SiO 4 ) nanocrystals by MSS in molten NaCl, 19 but found that the formation of periclase phase as a by-product still could not be avoided.…”

Forsterite powders with controllable morphology were synthesized using oxides as raw materials in NaCl-KCl molten salt media. The effects of MgO/SiO 2 ratio, calcining temperature, and salt/oxide ratio on the phase composition and morphology of the powders are investigated. The results indicate that single-phase forsterite powders can be synthesized from a mixture of MgO and SiO 2 with a MgO/ SiO 2 molar ratio of 2:1.3 at 700°C. With the increase of calcining temperature, the powders obtained changes from an irregular to a columnar morphology. In addition, the morphology of the forsterite powders produced can also be controlled by altering the salt/oxide ratio. K E Y W O R D Smorphology, powders, silicates, synthesis

“…Coprecipitation, mechanical mixing and hydrothermal synthesis are the most widely used methods to prepare ZrTiO 4 composite particles [12][13][14][15][16][17]. Kimura et al [18] synthesized the needle like ZrTiO 4 powder through the molten salt synthesis technique. Kim and Jang [19] studied the nano-structural characteristics of ZrTiO 4 based dielectrics by the Raman line-shape parameters using the phonon confinement model.…”
