Zirconium tungstate (ZrW2O8) has attracted much attention as a promising nanofiller due to its strong isotropic negative thermal expansion. Since the first report on ZrW2O8, numerous synthetic approaches have been investigated to control the morphology of the particles. Among them, introduction of precursor ZrW2O7(OH)2·2H2O to prepare ZrW2O8 particles has emerged as a promising tool to yield rod shaped microparticles, which cannot be obtained by direct solid state reaction of ZrO2 and WO3. However, despite size and shape dependent properties of the nanocrystals, synthesis of nanosized ZrW2O8 is one of the major challenges to date. In our work, we report on the formation of size controlled zirconium tungstate particles and their application as a nanofiller for reduced thermal expansion of nanocomposites. |
