Preparation method of refractory material and refractory material
The invention discloses a preparation method of a refractory material and the refractory material, and relates to the technical field of refractory materials. The technical problems that in the prior art, a refractory material suitable for precision casting of titanium, zirconium and an alloy thereof is complex in obtaining process and high in cost, and when titanium, zirconium and the alloy thereof are used for casting some narrow gaps, runners, cavities, air channels and other spaces, a ceramic core is difficult to clean are solved. The preparation method of the refractory material comprises the following steps: uniformly mixing calcium carbonate and yttrium oxide according to a molar ratio of 1: (2-4) to obtain a mixture; drying the mixture to form powder; carrying out wet ball milling on the powder, and drying at constant temperature to form powder for more than or equal to 48 hours after the wet ball milling; 5% by weight of a polyvinyl alcohol binder is added into the powder for granulation and sieving to form a blank, and the blank is pressed and then dried to form a blank body; and sintering the blank at high temperature. The refractory material disclosed by the invention has excellent stability, high refractoriness and strength, and kerosene has a self-collapsing characteristic.
本申请公开了一种耐火材料的制备方法及耐火材料，涉及耐火材料技术领域。本申请解决了现有技术中适用于钛锆及其合金精铸的耐火材料获取工艺复杂、成本高以及钛锆及其合金铸造某些窄间隙、流道、空腔、气道等空间时存在陶瓷型芯清芯困难的技术问题。该耐火材料的制备方法包括将碳酸钙和三氧化二钇按照1:2‑4的摩尔比例混匀成混合物；将混合物烘干形成粉料；将粉料进行湿态球磨，湿态球磨后恒温干燥形成粉体，粉体干燥≥48小时；将重量5％的聚乙烯醇粘结剂加到粉体内进行造粒、过筛形成胚料，胚料压制后干燥形成胚体；将胚体进行高温烧结。本申请的耐火材料具有优异的稳定性，该耐火材料具有高的耐火度和强度，见煤油具有自溃散特性。
