N2 - Zirconium tungstate (ZrW2O8) is a ceramic that shows a large isotropic negative thermal expansion over a wide range of temperatures. This unique property makes it an interesting candidate for such applications in which thermal expansion mismatch between components constitutes a problem. A novel precursor for ZrW2O8 made from relatively cheaper and abundant starting chemicals, namely zirconium acetate (ZrAc) and tungstic acid (TA) were prepared. The solution parameters were investigated (i.e. solubility of tungstic acid, adjustment of the stoichiometry, final pH of the solution, ageing time). After two steps of heat treatment, phase pure ZrW2O8 powder was produced. The characterization of produced powders was carried out.
