Microcrystalline alumina grinding medium and preparation method thereof
The invention discloses a microcrystalline aluminum oxide grinding medium which comprises the following components: ceramic metal oxide and clay in a mass ratio of (18-19): (1-2), wherein the ceramic metal oxide is a composite oxide of an aluminum element, a magnesium element and a calcium element, and the molar ratio of the aluminum element to the magnesium element to the calcium element is (44.5-97.5): (1.2-2.1): (0.88-0.92). The invention discloses a preparation method of the microcrystalline alumina grinding medium, which comprises the following steps: dissolving the water-soluble aluminum salt, the water-soluble magnesium salt and the water-soluble calcium salt in water, adjusting the system to be alkaline, and roasting the precipitate at the roasting temperature of 900-1000 DEG C to obtain a ceramic metal oxide; the preparation method comprises the following steps: adding the ceramic metal oxide and the clay into water, uniformly mixing, adding the polyvinyl alcohol, uniformly mixing to obtain slurry, performing spray granulation, molding, and sintering at 1400-1500 DEG C to obtain the microcrystalline aluminum oxide grinding medium.
本发明公开了一种微晶氧化铝研磨介质，其组分包括：陶瓷金属氧化物和黏土，陶瓷金属氧化物和黏土的质量比为18‑19：1‑2；其中，陶瓷金属氧化物为铝元素‑镁元素‑钙元素的复合氧化物，铝元素、镁元素、钙元素的摩尔比为44.5‑97.5：1.2‑2.1：0.88‑0.92。本发明公开了上述微晶氧化铝研磨介质的制备方法，包括如下步骤：将水溶性铝盐、水溶性镁盐、水溶性钙盐溶于水中，调节体系成碱性，将沉淀进行焙烧，焙烧温度为900‑1000℃，得到陶瓷金属氧化物；将陶瓷金属氧化物和黏土加入水中混合均匀，再加入聚乙烯醇混合均匀得到浆料，然后喷雾造粒，成型，1400‑1500℃烧结得到微晶氧化铝研磨介质。
