High-iron-content wear-resistant ceramic grinding ball
The invention discloses a wear-resistant ceramic grinding ball with high iron content. The wear-resistant ceramic grinding ball comprises the following raw materials in percentage by mass: 5-15% of bauxite, 20-60% of iron oxide, 20-65% of gamma-aluminum oxide, 1-5% of silicon oxide, 1-10% of zirconium oxide, 0.5-5% of zinc oxide, 0.1-0.5% of chromium oxide, 0.2-3% of cerium oxide, 1-5% of feldspar, 1-3% of talc, 0.5-3% of calcium carbonate and 0.2-2% of barium carbonate. According to the invention, the problem of low-cost production of high-specific-gravity ceramic grinding balls is solved, the problem of reduction of wear resistance, strength and hardness of a ceramic material caused by application of a large amount of iron oxide is solved, and the problem of conversion of iron oxide into a spinel mineral AB2X4 with relatively high hardness at a relatively low temperature is also solved.
本发明公开了一种高铁含量耐磨陶瓷研磨球，包括以下质量百分比的原料：铝矾土5~15%，氧化铁20~60%，γ~氧化铝20~65%，氧化硅1~5%，氧化锆1~10%，氧化锌0.5~5%，氧化铬0.1~0.5%，氧化铈0.2~3%，长石1~5%，滑石1~3%，碳酸钙0.5~3%，碳酸钡0.2~2%。本发明既解决了低成本生产高比重陶瓷研磨球的问题，又解决了大量应用氧化铁导致陶瓷材料耐磨性、强度以及硬度下降的问题，还解决了较低温度下将转氧化铁转化为硬度较高的尖晶石族矿物AB2X4问题。
