Method for preparing yttrium oxide refractory material product through gel casting and crucible
The invention belongs to the technical field of refractory materials, and particularly relates to a method for preparing an yttrium oxide refractory material product through gel casting and a crucible. Aiming at the problem that pure-phase yttrium oxide is only suitable for preparing a crucible with a relatively small size and cannot meet the smelting and casting requirements of a large-size cast ingot, the invention provides the method for preparing the yttrium oxide refractory material product, which is simple in preparation process, controllable in size and excellent in performance, and four kinds of Y2O3 particles or micron fine powder with different sizes are adopted; y2O3 with different sizes is added according to a reasonable sequence and proportion, and the obtained product has good mechanical properties and thermal shock resistance at the same time. Meanwhile, by combining the reasonable selection of the dispersing agent and the suspending agent and the precise system of glue discharging and sintering, the finally obtained product, especially the yttrium oxide crucible, has excellent comprehensive performance.
本发明属于耐火材料技术领域，具体涉及一种凝胶注模成型制备氧化钇耐火材料制品的方法及坩埚。针对纯相的氧化钇只适合制备尺寸相对较小的坩埚，无法满足大尺寸铸锭的熔炼与铸造的需求的问题，本发明提出了一种制作工艺简单、尺寸可控、性能优良的制备氧化钇耐火材料制品的方法，采用四种不同尺寸的Y2O3颗粒或微米细粉，将不同尺寸的Y2O3按照合理的顺序和配比加入，所获得制品同时具有良好的力学性能和抗热震性能。同时结合分散剂和悬浮剂的合理选择，排胶及烧结的精确制度，最终获得的制品，特别是氧化钇坩埚具有优良的综合性能。
