Abstract In this study, Gd₂(Hf₀.₇Ti₀.₃)₂O₇ ceramics were synthesized by a high‐temperature solid‐state method, and the feasibility of using it as thermal barrier coating was systematically studied. This study primarily investigated physical properties, mechanical calcium–magnesium–alumina–silicate oxides (CMAS) corrosion resistance ceramic bulk. The results indicated that expansion coefficient close to 6∼8wt% yttria‐stabilized zirconia (YSZ). At 1000°C, conductivity (1.43 W/(m·K)) about 43% lower than YSZ (2.5 W/(m·K)). Furthermore, also exhibited significant advantages in properties. Its hardness, fracture toughness, Young's modulus are 10.00 ± 0.28 GPa, 2.53 0.06 MPa·m¹/ 2 , 124.91 17 respectively. addition, excellent CMAS resistance, making promising candidate for next generation materials.
