Sintering-resistant high-CMAS-corrosion-resistant high-entropy tantalum/niobium ceramic and preparation method thereof
The invention discloses anti-sintering high-CMAS corrosion-resistant high-entropy tantalum/niobium ceramic and a preparation method thereof. According to the sintering-resistant high-entropy tantalum/niobium ceramic with the strong CMAS corrosion resistance, the sintering-resistant high-entropy tantalum/niobium ceramic with the strong CMAS corrosion resistance is specifically prepared through the steps that CoO powder, NiO powder, MgO powder, CaO powder, a TaCl5 solution and an NbCl5 solution serve as raw materials, needed precipitated colloid is prepared through a chemical coprecipitation method, finally, blocks are obtained through high-temperature calcination, and the corresponding preparation method is adopted. The high-entropy tantalum/niobium ceramic with high sintering resistance and CMAS corrosion resistance can be prepared, and the tantalum/niobium ceramic has all the characteristics of the single tantalum/niobate ceramic and has the characteristics of sintering resistance, extremely high CMAS corrosion resistance and excellent fracture toughness.
本发明公开了一种抗烧结强抗CMAS腐蚀高熵钽/铌陶瓷及其制备方法。本发明通过抗烧结强抗CMAS腐蚀高熵钽/铌陶瓷，所述抗烧结强抗CMAS腐蚀高熵钽/铌陶瓷具体为以CoO粉末，NiO粉末，MgO粉末，CaO粉末，TaCl5溶液以及NbCl5溶液为原料，通过化学共沉淀法制备出所需的沉淀胶体，最后通过高温煅烧获得块体，以及相应的制备方法；可以制得一种抗烧结强抗CMAS腐蚀高熵钽/铌陶瓷，并且具有上述单一钽/铌酸盐陶瓷的所有特点，以及具有抗烧结、极强抗CMAS腐蚀、极好的断裂韧性的特性。
