Gadolinium zirconate/gadolinium tantalate composite ceramic and preparation method thereof
The invention belongs to the technical field of inorganic non-high-temperature composite ceramic materials, and particularly relates to a gadolinium zirconate/gadolinium tantalate composite ceramic and a preparation method thereof, wherein the raw materials used by the ceramic are gadolinium oxide, zirconium oxide and tantalum oxide. The preparation method comprises the following steps: preparing composite raw materials gadolinium zirconate and gadolinium tantalate, weighing the raw materials in proportion, mixing the prepared raw materials in absolute ethyl alcohol, putting the mixture into a planetary ball mill, carrying out ball milling, uniformly mixing, drying the mixed powder, and sintering; and cooling, taking out the sintered gadolinium zirconate and gadolinium tantalate samples, grinding, weighing according to a composite ratio, carrying out ball milling, drying, compacting the dried powder in a mold, and sintering. According to the invention, the method is high in process purity, low in impurity content, low in product preparation cost and suitable for batch production, and the target product has good thermophysical performance and is expected to serve as a novel high-temperature-resistant, anti-oxidation, anti-corrosion and anti-ceramic material.
本发明属于无机非高温复合陶瓷材料技术领域，具体涉及一种锆酸钆/钽酸钆复合陶瓷及其制备方法。陶瓷所用原料为氧化钆、氧化锆和氧化钽，分别制备复合原材料锆酸钆和钽酸钆，按比例称量原料，将配好的原料在无水乙醇中混合后置于行星式球磨机中球磨，使其能够混合均匀，将混合后的粉末干燥后进行烧结；冷却取出烧结后的锆酸钆和钽酸钆样品进行研磨、按复合比例称量、球磨、干燥，将干燥后的粉末置于模具内压实，然后进行烧结。本发明工艺纯度高，杂质含量低，产品制备成本低，适合批量生产，目的产品具有良好的热物理性能，有望作为新型耐高温，抗氧化，抗腐蚀抗陶瓷材料。
