Synthesis conditions and sintered ZrW2O8 structure

Abstract

This paper discusses synthesis condition effect on the structure and morphology of ZrW₂O₈ using thermal decomposition of precursor ZrW₂O₇(OH,Cl)₂·2H₂O prepared by hydrothermal method. It was observed that for hydrothermal precursor synthesis the optimal concentration of hydrochloric acid in the reaction mixture was about 2.3 M and sintering time amounted to 36 hours. The precursor morphology was in the form of needle-like particles and loose irregular shape agglomerates. The pure nanoscale ZrW₂O₈ powder was obtained by precursor heating at 570°C for 1 hour and has needle-like particles with an intrinsic block structure. The average block size was 50 nm. The average transverse size was less than 1 μm, the longitudinal particle size varied from 500 to 5000 nm.
