High-aluminum ceramic filler prepared from gamma aluminum oxide and preparation method of high-aluminum ceramic filler
The invention discloses a high-aluminum ceramic filler prepared from gamma aluminum oxide and a preparation method of the high-aluminum ceramic filler. The high-aluminum ceramic filler is prepared from 83-94 wt% of an aluminum oxide raw material with a main crystal phase being gamma-Al2O3, 2-5 wt% of a borate mineral or a synthesized borate compound, 1-4 wt% of ball clay, 1-4 wt% of nano silicon dioxide, 1-4 wt% of a calcium-magnesium complex mineral and 0-7 wt% of calcined aluminum oxide powder. According to the invention, the technological process is simplified, the procedure of converting gamma-Al2O3 into alpha-Al2O3 through calcination is not needed, the high-aluminum ceramic filler is directly prepared from gamma-Al2O3, carbon emission and energy consumption are greatly reduced, the product percent of pass is high, and the performance reaches or exceeds the standard requirement of the chemical industry. The high-aluminum ceramic filler can be used as a supporting or covering material for chemical reaction tower (device) beds in petrochemical industry, coal chemical industry, chemical fertilizer, nonferrous metallurgy and the like.
一种用γ氧化铝制备的高铝陶瓷填料及其方法，其配方为：主晶相为γ‑Al2O3的氧化铝原料83~94wt%，硼酸盐矿物或合成的硼酸盐化合物2~5wt%，球粘土1~4wt%，纳米二氧化硅1~4wt%，钙镁复合矿物1~4wt%，煅烧氧化铝粉0~7wt%。本发明简化了工艺流程，无需经过γ‑Al2O3煅烧转变为ɑ‑Al2O3的工序，直接由γ‑Al2O3制备高铝陶瓷填料，大大降低了碳排放和能源消耗，且产品合格率高，性能达到或超过化工行业标准要求。可用于石油化工、煤化工、化肥、有色冶炼等化工反应塔（器）床层的支撑或覆盖材料。
