Preparation method of anti-sintering YTaO4 ceramic powder
The invention belongs to the technical field of refractory materials, and relates to a preparation method of anti-sintering YTaO4 ceramic powder. The preparation method of the anti-sintering YTaO4 ceramic powder comprises the following steps of mixing tantalum oxide or tantalum hydroxide with yttrium oxide or yttrium carbonate to obtain mixed powder, wherein the mixing mode is ball-milling mixing, and the parameters of the ball-milling mixing are as follows: the mass ratio of balls to materials is (4-12): 1, the revolution rate is 100-500 rpm, the rotation rate is 100-600 rpm, and the time is 1-24 hours, placing the mixed powder in an electric arc furnace for electric melting, enabling the raw materials to react in the melt for a period of time and then cooling along with the furnace, and acquiring a YTaO4 block, and then through crushing and sieving, acquiring the YTaO4 ceramic powder. The powder prepared by the method not only has the intrinsic characteristic of YTaO4, but also has excellent thermophysical property and also has the characteristics of high purity, low activity, sintering resistance and the like.
本发明属于耐火材料技术领域，涉及一种抗烧结YTaO4陶瓷粉体的制备方法。涉及的一种抗烧结YTaO4陶瓷粉体的制备方法将氧化钽或氢氧化钽与氧化钇或碳酸钇混合，得到混合粉体；混合的方式为球磨混合，球磨混合的参数包括：球料质量比为4～12:1，公转速率100～500 rpm，自转速率100～600 rpm，时间1～24小时；将混合粉体置于电弧炉中进行电熔，原料在熔体中反应一段时间后随炉冷却得到YTaO4块体；再经粉碎和过筛，得到所述YTaO4陶瓷粉体。该法所制备的粉体不仅具有YTaO4本征特性，热物性优异；还具有纯度高、活性低、抗烧结等电熔材料的特点。
