High-density zirconium tungstate solid solution ceramic and preparation method thereof
The invention relates to a high-density zirconium tungstate solid solution ceramic and a preparation method thereof, and belongs to the technical field of zirconium tungstate solid solution ceramics, the chemical formula of the zirconium tungstate solid solution ceramic is ZrW2-xMoxO8, 0 < = x < = 1, and the zirconium tungstate solid solution ceramic is of a simple cubic lattice and is of a skeleton net structure composed of a WO4 or MoO4 tetrahedron and a ZrO6 octahedron which share the same vertex angle. According to the high-density zirconium tungstate solid solution ceramic and the preparation method thereof, a zirconium tungstate solid solution precursor is synthesized at low temperature by adopting a combined method of a sol-gel method and a hydrothermal method, and then the high-density zirconium tungstate solid solution ceramic is rapidly prepared at low temperature by adopting a discharge plasma sintering method. Compared with zirconium tungstate prepared by a traditional 1250 DEG C solid-phase reaction method, the method has the advantages that the sintering temperature is lower, and the prepared high-density zirconium tungstate solid solution ceramic does not generate zirconium oxide, tungsten oxide and other impure substances.
本发明涉及一种高致密钨酸锆固溶体陶瓷及其制备方法，属于钨酸锆固溶体陶瓷技术领域，所述钨酸锆固溶体陶瓷的化学式为ZrW2‑xMoxO8，其中，0≤x≤1，所述钨酸锆固溶体陶瓷为简单立方点阵，是由共顶角的WO4或MoO4四面体与ZrO6八面体组成的骨架网状结构。本发明提供一种高致密钨酸锆固溶体陶瓷及其制备方法，采用溶胶凝胶法和水热法的联合方法低温合成钨酸锆固溶体前驱体，然后通过放电等离子体烧结方法低温快速制备出高致密钨酸锆固溶体陶瓷，该方法较传统1250℃固相反应法制备的钨酸锆相比，烧结温度更低，而且制备出的高致密钨酸锆固溶体陶瓷没有生成氧化锆和氧化钨等不纯物质。
