摘要
A compound tentatively denoted as Zn2Ti,3O8 is determined to be a low-temperature form of ZnTiO3. At a heating rate of 10°C·min−1 the low-temperature form crystallizes at 600° to 765° C from an amorphous material prepared by the simultaneous hydrolysis of zinc acetylacetonate and titanium isopropoxide. It has a cubic unit cell with a =0.8408 nm. The cubic-to-hexagonal transformation occurs slowly above 820°C; during transformation ZnTiO3 decomposes into Zn2TiO4 and TiO2 (rutile) at 965° to 1010°C. A single phase of the hexagonal form can be prepared by heating for 5 h at 900°C. The structure of both forms consists of octahedral TiO6 groups.
