摘　　要：铝电解用炭素阳极容易在高温下发生氧化反应,造成炭素阳极的消耗量较大,生产成本较高。针对该情况利用纳米陶瓷基高温防氧化涂层材料在阳极炭块表面形成致密的抗氧化保护涂层,验证涂料对阳极炭块的保护作用,探索延长阳极炭块使用寿命,降低炭耗、CO_(2)排放的新路径。工业化试验结果表明该涂层的高温防氧化性较好,能有效实现对炭素阳极的保护。Carbon anode for aluminum electrolysis is prone to oxidation reaction at high temperature,which results in large consumption of carbon anode and high production cost.In view of this situation,nano ceramic based high temperature anti-oxidation coating material is used to form a dense anti-oxidation protective coating on the surface of anode carbon block,verify the protective effect of coating on anode carbon block,explore a new path to extend the service life of anode carbon block,reduce carbon consumption and carbon dioxide emissions.The industrial test results show that the coating has good oxidation resistance at high temperature and can effectively protect carbon anode.
