High-strength zirconium silicate composite ceramic grinding medium and preparation method thereof
The invention provides a high-strength zirconium silicate composite ceramic grinding medium and a preparation method thereof, and belongs to the field of ceramics, the high-strength zirconium silicate composite ceramic grinding medium comprises the following components by percentage: 60%-75% of zirconite, 10%-15% of ceramic waste, 5%-10% of silicon carbide powder, 0%-8% of bauxite, 2%-5% of dolomite, 1%-3% of barium carbonate, 1%-2% of yttrium oxide, 2%-3% of montmorillonite, 0%-3% of alumina, 0%-3% of magnesium oxide, 2%-4% of a dispersant, and 2%-4% of a binder. The binder is one or a mixture of more of zirconium oxide, aluminum oxide or aluminum silicate. The ceramic waste is used for replacing part of zirconite, consumption of zirconite is reduced, the production cost of enterprises is reduced, the raw material cost is low, the preparation method is simple, the prepared high-strength zirconium silicate composite ceramic mill is high in dielectric strength, and the abrasion of the high-strength zirconium silicate composite ceramic mill is superior to that of conventional zirconium silicate beads; the service life is longer than that of conventional zirconium silicate beads, the cost is greatly reduced compared with that of the conventional zirconium silicate beads, and a new utilization mode is provided for the ceramic waste, so that the ceramic waste can be reutilized.
本发明提供一种高强度硅酸锆复合陶瓷磨介及其制备方法，属于陶瓷领域，按照百分配比包括：锆英石60%—75%、陶瓷废料10%—15%、碳化硅粉末5%—10%、铝矾土0%—8%、白云土2%—5%、碳酸钡1%—3%、氧化钇1%—2%、蒙脱石2%—3%、氧化铝0%—3%、氧化镁0%—3%、分散剂2%—4%、粘结剂2%—4%，所述粘结剂采用氧化锆、氧化铝或硅酸铝中的一种或多种混合。通过采用陶瓷废料代替一部分锆英石的使用，减少锆英石的消耗，降低了企业的生产成本，且原材料成本低，制备方法简单，制备获得的高强度硅酸锆复合陶瓷磨介强度高，其磨耗优于常规硅酸锆珠；使用寿命较常规硅酸锆珠更长，成本较常规硅酸锆珠大幅度降低，且为陶瓷废料提供一个新的利用方式，使陶瓷废料可以二次利用。
