ZTA ceramic granulation powder and preparation method and application thereof
The invention discloses ZTA ceramic granulation powder, a preparation method of the ZTA ceramic granulation powder and application of the ZTA ceramic granulation powder to compact forming and firing for manufacturing porcelain parts. The ZTA ceramic granulation powder is prepared from the following raw materials in parts by weight: 80 to 90 parts of alpha-Al2O3 powder, 10 to 20 parts of ZrO2 powder, 0.05 to 1.5 parts of doped powder, 0.1 to 0.45 part of TiO2 powder, 45 to 60 parts of pure water, 0.5 to 2.5 parts of cold-soluble polyvinyl alcohol binding agent and 0.5 to 3.5 parts of polyethylene wax emulsion through pulping and spray granulation, the doped powder is at least one of MgO powder, Cr2O3 powder and CeO2 powder; and the TiO2 powder is rutile type titanium dioxide. The ZTA ceramic granulation powder disclosed by the invention is round in appearance and excellent in flowability and loose index, and a ZTA porcelain piece formed by compacting, molding and high-temperature firing of the granulation powder is white, and has lower porcelain forming temperature and better fracture toughness performance.
本发明公开了一种ZTA陶瓷造粒粉、其制备方法以及用于压坯成型和烧成制作瓷件中的应用。ZTA陶瓷造粒粉由包括以下组分的原料制浆喷雾造粒获得：α‑Al2O3粉体80～90重量份，ZrO2粉体10～20重量份，掺杂粉体0.05～1.5重量份，TiO2粉体0.1～0.45重量份，纯水45～60重量份，冷溶型聚乙烯醇结合剂0.5～2.5重量份，聚乙烯蜡乳液0.5～3.5重量份；掺杂粉体为MgO粉体、Cr2O3粉体、CeO2粉体中的至少一种；TiO2粉体为金红石型钛白粉。本发明ZTA陶瓷造粒粉形貌圆整，流动性和松装指标优良，该造粒粉经压坯成型和高温烧成的ZTA瓷件颜色显白色，具有更低的成瓷温度和更佳的断裂韧性性能。
