摘要：In the study, Zr0.5Hf0.5V2−xPxO7 (0 ≤ x ≤ 1.2) was prepared by solid state method and then the microstructure of synthesized samples was investigated. The microstructure, coefficient of thermal expansion (CTE) and phase transition of Zr0.5Hf0.5V2−xPxO7 (0 ≤ x ≤ 1.2) were investigated with thermal dilatometry, x-ray diffraction (XRD) and Raman spectroscopy. The results showed that the samples were single cubic phase with the space group of Pa3¯ in the crystal structure. When the substitution rate of P5+ was higher than 0.6, the 3 × 3 × 3 superstructure disappeared. The expansion coefficient of Zr0.5Hf0.5V1.2P0.8O7 was calculated to be −0.53 × 10−6 K−1 under the linear thermal expansion in a very wide temperature range from 300 to 573 K. With the increase of P5+ content, the temperatures of positive-to-negative thermal expansion of Zr0.5Hf0.5V2−xPxO7 firstly even decreased below room temperature and then increased. The synthesized Zr0.5Hf0.5V2−xPxO7 exhibited near zero thermal expansion behavior in a wide temperature range around room temperature. © 2018 Elsevier Ltd
