ZrP2O7is a promising material for high temperature insulating applications. However, decomposition above 1400 °C is the bottleneck that limiting its application at high temperatures. To improve the thermal stability, a novel multicomponent equimolar solid solution (TiZrHf)P2O7was designed and successfully synthesized in this work inspired by high-entropy ceramic (HEC) concept. The as-synthesized (TiZrHf)P2O7exhibits good thermal stability, which is not decomposed after heating at 1550 °C for 3 h. It also shows lower thermal conductivity (0.78 W m−1K−1) compared to the constituting metal pyrophosphates TiP2O7, ZrP2O7and HfP2O7. The combination of high thermal stability and low thermal conductivity renders (TiZrHf)P2O7promising for high temperature thermal insulating applications.
