Submicron spherical zirconium oxide powder, preparation method thereof and zirconium oxide ceramic
The invention provides submicron spherical zirconium oxide powder, a preparation method and zirconium oxide ceramic, raw materials for preparing the zirconium oxide powder comprise a main material and a dispersing agent, the main material comprises zirconium oxychloride, urea and pure water, the component ratio of the main material is zirconium oxychloride: urea: pure water = (45-51): (9-15): 40, and the dispersing agent is a dispersant. The dispersing agent accounts for 0-5% of the mass of the main material; the zirconium oxide powder is prepared by the following steps: S1, mixing raw materials; S2, reacting and crystallizing; and S3, removing impurities. The preparation method of the prepared submicron spherical zirconium oxide powder is simple in process and low in production cost, and the zirconium oxide powder is less in agglomeration, high in sphericity degree and narrower in particle size distribution.
本发明提供了一种亚微米级球形氧化锆粉体、制备方法及氧化锆陶瓷，制备所述氧化锆粉体的原料包括主料和分散剂，所述主料包括氯氧化锆、尿素和纯水，所述主料的组分比例按重量份计为氯氧化锆：尿素：纯水＝45‑51:9‑15:40，所述分散剂为主料质量的0‑5％；所述氧化锆粉体经过S1原料混合、S2反应析晶、S3去除杂质。制得的亚微米级球形氧化锆粉体的制备方法，工艺简单、生产成本低、所述氧化锆粉体的团聚较少且球形度高且粒径分布较窄。
