Preparation method of composite nano ZrO2 powder microspheres with high sintering activity
The invention discloses a preparation method of high-sintering-activity composite nano ZrO2 powder microspheres, and particularly relates to the technical field of ZrO2 powder microsphere preparation. The high-sintering-activity composite nano ZrO2 powder microspheres are composed of, in parts by weight, 18-22 parts of zirconium oxychloride powder, 8-12 parts of acetylacetone, 10-20 parts of formaldehyde, 6-10 parts of urea, 16-18 parts of nanoscale magnesium oxide powder and 14-18 parts of nanoscale aluminum oxide powder. The used auxiliary materials (in parts by weight) comprise 8-10 parts of ammonia water, 8-10 parts of dilute nitric acid and 20-40 parts of distilled water. Nanoscale magnesium oxide powder, nanoscale aluminum oxide powder and prepared powder are mixed and ground, and then the mixed powder is sintered, so that the nanoscale magnesium oxide powder and the nanoscale aluminum oxide powder can generate magnesium-aluminum spinel crystals, and the generated magnesium-aluminum spinel crystals are expanded in volume and can fill holes; therefore, holes formed in the surfaces of the zirconium dioxide powder microspheres can be blocked, and the sintering activity of the zirconium dioxide powder microspheres is improved.
本发明公开了高烧结活性复合纳米Zr02粉末微球的制备方法，具体涉及Zr02粉末微球制备技术领域，所使用原料(按重量份数计)包括氧氯化锆粉末18‑22份、乙酰丙酮8‑12份、甲醛10‑20份、尿素6‑10份、纳米级氧化镁粉末16‑18份、纳米级氧化铝粉末14‑18份，所使用辅料(按重量份数计)包括氨水8‑10份、稀硝酸8‑10份、蒸馏水20‑40份。本发明将纳米级氧化镁粉末、纳米级氧化铝粉末和制备的粉末混合研磨，然后再对混合粉末进行烧结，使得纳米级氧化镁粉末能够与纳米级氧化铝粉末能够生成镁铝尖晶体，而且产生的镁铝尖晶体体积膨胀能够填充孔洞，从而能够堵塞二氧化锆粉末微球表面所形成的孔洞，以提高二氧化锆粉末微球的烧结活性。
