Method for modifying nano zirconium oxide powder by wet process
The invention discloses a method for modifying nano zirconium oxide powder by a wet process, and belongs to the field of functional ceramics. After the modified zirconium oxide is sintered, the powder loss amount is far lower than that of the original zirconium oxide ceramic, the ceramic is uniform and compact and has no large-size pores, the mechanical property and the density of the modified zirconium oxide ceramic are superior to those of the original zirconium oxide ceramic, and the purpose of improving the sintering performance is achieved. As a novel forming method, gel casting provides an effective technical approach for preparing ceramic products with large sizes and complex shapes.
本发明公开了一种湿法改性纳米氧化锆粉体方法，属于功能陶瓷领域。改性后的氧化锆烧结后粉体流失量要远低于原始氧化锆陶瓷，陶瓷均匀致密，而且没有大尺寸的孔隙，且改性氧化锆陶瓷的力学性能以及致密度都有优于原始氧化锆陶瓷，达到了提高烧结性能的目的。凝胶注模作为一种新颖的成型方法，为制备大尺寸及复杂形状的陶瓷制品提供了有效的技术途径。
