Alumina ceramic microbead green body with high sphericity degree and preparation method of alumina ceramic microbead green body
The invention relates to the technical field of superfine grinding medium materials, in particular to an aluminum oxide ceramic microbead blank with a high sphericity degree and a preparation method of the aluminum oxide ceramic microbead blank. The preparation method comprises the following steps: mixing aluminum oxide ceramic slurry, a dispersing agent and a bonding aid to obtain ceramic microbead blank slurry; dripping the ceramic microbead green body slurry on the surface of a carrier with a super-hydrophobic medium, and carrying out rolling forming under a preset vibration condition to obtain an aluminum oxide ceramic microbead green body; drying the alumina ceramic microbead green body to obtain an alumina ceramic microbead green body; the preset vibration condition comprises preset vibration frequency and preset vibration time, the preset vibration frequency is larger than or equal to 100 times/min, and the preset vibration time is larger than or equal to 3 min; according to the preparation method, based on the characteristic of lotus leaf self-cleaning effect of the super-hydrophobic medium, ceramic microbead blank slurry can be promoted to form an aluminum oxide microbead blank with the sphericity degree generally being 0.94 or above.
本申请涉及超细研磨介质材料技术领域，尤其涉及一种具有高球形度的氧化铝陶瓷微珠坯体及其制备方法；所述制备方法包括：将氧化铝陶瓷料浆、分散剂和粘结助剂进行混合，以得到陶瓷微珠坯体料浆；使陶瓷微珠坯体料浆滴落于具有超疏水介质的载具表面，同时在预设振动条件下进行滚动成型，以得到氧化铝陶瓷微珠生坯；对氧化铝陶瓷微珠生坯进行干燥，以得到氧化铝陶瓷微珠坯体；预设振动条件包括预设振动频率和预设振动时间，预设振动频率≥100次/min，预设振动时间≥3min；该制备方法基于超疏水介质所具有的“荷叶自洁效应”的特性，可以促使陶瓷微珠坯体料浆形成球形度普遍在0.94以上的氧化铝微珠坯体。
