Lanthanum zirconate (LZO) ceramic foams with hierarchical pore structure were fabricated by particle‐stabilized foaming method for the first time, and the as‐prepared ceramics have high porosity of 90.7%‐94.9%, low thermal conductivity, and relatively high compressive strength. The LZO powder was synthesized by solid‐state method. The porosity of the ceramic foams was tailored by suspensions with different solid loadings (20‐40 wt%). The sample with porosity of 94.9% has thermal conductivity of 0.073 W/(m·K) and compressive strength of 1.19 MPa, which exhibits outstanding property of thermal insulation and mechanical performance, indicating that LZO ceramic foam is a promising thermal insulation material in high temperature applications.

颗粒稳定的泡沫具有低导热性的多层多孔锆酸镧泡沫

首次通过颗粒稳定发泡法制备了具有分层孔结构的锆酸镧（LZO）陶瓷泡沫，所制备的陶瓷具有90.7％-94.9％的高孔隙率，低导热率和相对较高的抗压强度。LZO粉末是通过固态方法合成的。陶瓷泡沫的孔隙率是通过具有不同固含量（20-40 wt％）的悬浮液量身定制的。孔隙率为94.9％的样品的热导率为0.073 W /（m·K），抗压强度为1.19 MPa，具有出色的隔热性能和机械性能，这表明LZO陶瓷泡沫是一种有希望的高隔热材料。温度应用。
