Preparation method of ZTA ceramic microbeads with adjustable particle sizes
The invention relates to the technical field of ceramic materials, in particular to a preparation method of ZTA ceramic microbeads with adjustable particle sizes. The preparation method of the ZTA ceramic microbeads with the adjustable particle size comprises the following steps: (1) mixing aluminum oxide powder, zirconium oxide, clay, magnesium oxide and rare earth oxide to obtain ceramic powder,and adding PVA accounting for 0.3-2.0% of the total mass of the ceramic powder; (2) putting the mixed powder into a ball mill, and carrying out ball milling to obtain slurry; (3) atomizing and granulating the slurry through a centrifugal spray tower to prepare spherical granulated powder; (4) removing iron from the spherical granulated powder; and (5) putting the spherical granulated powder subjected to iron removal into a high-temperature sagger, and putting the high-temperature sagger into a pushed slab kiln for calcining to obtain the ZTA ceramic microbeads. According to the preparation method disclosed by the invention, industrial large-scale production of the ZTA ceramic microspheres is realized, the sphere diameter can be controlled by adjusting various process conditions, and the prepared ZTA ceramic microspheres are high in sphericity degree.
本发明涉及陶瓷材料技术领域，具体涉及一种颗粒尺寸可调的ZTA陶瓷微珠的制备方法。所述的颗粒尺寸可调的ZTA陶瓷微珠的制备方法，步骤如下：(1)将氧化铝粉、氧化锆、粘土、氧化镁、稀土氧化物混合得到陶瓷粉料，并加入陶瓷粉料总质量0.3‑2.0％的PVA；(2)将混合后的粉料放入球磨机中球磨制成料浆；(3)将料浆经离心喷塔雾化造粒，制成球形造粒粉；(4)将球形造粒粉进行除铁；(5)将除铁后的球形造粒粉装入高温匣钵放入推板窑中进行煅烧，得到ZTA陶瓷微珠。本发明的制备方法实现了工业规模化生产ZTA陶瓷微球，而且可以通过调整多种工艺条件控制球径大小，制备的ZTA陶瓷微珠球形度高。
