Thermal barrier ceramic coating material and preparation method thereof
The invention discloses a thermal barrier ceramic coating material which is rare earth tantalate RETa3O9 spherical powder, and the particle size of the thermal barrier ceramic coating material is 10-100 microns. The material is prepared by mixing a raw material and a fused salt, the mass ratio of the raw material to the fused salt is (1-10): (1-6), the molar ratio of the rare earth oxide RE2O3 to the tantalum pentoxide Ta2O5 in the raw material is 1: 3, and the mass ratio of the KCl to the NaCl in the fused salt is (1-6): (0-3). The thermal barrier ceramic coating material is high in sphericity rate and good in fluidity.
本发明公开了一种热障陶瓷涂层材料，为稀土钽酸盐RETa3O9球形粉体，粒径为10～100μm；由原料和熔盐混合制备而成，所述原料和熔盐的质量比为(1～10)：(1～6)，在所述原料中，所述稀土氧化物RE2O3和五氧化二钽Ta2O5的摩尔比为1：3，在熔盐中，所述KCl和NaCl的质量比为(1～6)：(0～3)。该热障陶瓷涂层材料球形率高，流动性好。
