摘　　要：采用遵义地区未能综合利用的锰渣制备陶瓷,同时添加稀土氧化镧,按一定配比制成稀土陶瓷,测试稀土元素对烧成温度的影响,并且对其抗压、抗弯性能以及吸水率进行测定,探讨了稀土氧化镧对锰渣陶瓷物理性能的控制。烧成温度随着稀土量的增加由1 220℃降低到1 135℃,在稀土添加量为6%时的抗压强度最高,添加稀土为10%的抗弯强度最高且吸水率最低。Waste manganese residue in Zunyi was used to fire ceramic with lanthanum oxide as additive. Effects of lantha- num oxide on firing temperature,compressive sthength,bending strength and water - absoption rate of the ceramic were investi- gated. The results show that firing temperature decreases from 1220℃ to 1135℃ with increase of lanthanum oxide content, compressive strength reaches the highest value when content of lanthanum oxide is 6% , and bending strength is the highest and water - absorption rate is the lowerest when lanthanum oxide content is 10% .
