Near-zero-expansion ceramic material with adjustable temperature range and preparation method of near-zero-expansion ceramic material
The invention provides a ZrMg (1-x) CaxMo3O12 ceramic material with an adjustable near-zero expansion temperature range and a preparation method thereof, analytically pure zirconium dioxide, magnesium oxide, calcium oxide and molybdenum trioxide are taken as raw materials, the raw materials are weighed according to the stoichiometric ratio of ZrMg (1-x) CaxMo3O12, ball milling and uniform mixing are carried out, then vacuum hot pressed sintering is carried out, and natural cooling is carried out to obtain the near-zero expansion ceramic material ZrMg (1-x) CaxMo3O12. The vacuum hot pressing method is adopted, the sintering temperature is reduced, the heat preservation time is shortened, and the purposes of saving energy, reducing consumption and reducing cost are achieved. On the other hand, the production cost is reduced to a great extent due to the introduction of calcium oxide.
本发明提供一种ZrMg1‑xCaxMo3O12近零膨胀温度范围可调的陶瓷材料及其制备方法，以分析纯的二氧化锆、氧化镁、氧化钙和三氧化钼为原料，按照ZrMg1‑xCaxMo3O12的化学计量比称取原料，球磨混合均匀，然后进行真空热压烧结，自然冷却得到所述近零膨胀陶瓷材料ZrMg1‑xCaxMo3O12。本发明采用真空热压法，降低了烧结温度，减少了保温时间，实现了节能减耗、降低成本目的。另一方面，氧化钙的引入在很大程度上也降低了生产成本。
