摘要
氧化铈是一种廉价而用途极广的新型功能材料,随着功能材料的不断发展,各种特殊物理性能的氧化铈的合成和性能越来越受到大家的关注。以氯化铈溶液为原料,加入一定量含肼盐添加剂,以草酸为沉淀剂,硝酸和草酸混合溶液对草酸铈沉淀进行浸泡或淋洗,结合缓慢升温灼烧,可以获得大比表面积、大粒度氧化铈,满足了客户需求。
Cerium oxide is a cheap but extremely useful new functional material. Along with the continuous development of functional materials, the synthesis and properties of various cerium oxide of special physical properties have been paid more and more attention. With the chlorinated cerium solution as raw materials, certain hydrazine salt as additives and oxalic acid as precipitation agent, to immerse or rinse, the oxalic acid cerium deposits are immersed and rinsed by mixture solution of nitric acid and oxalic , combined with the gradual thawing burning. Large specific surface area and large particle sizeof cerium oxide can be achieved which meets customers＇ need.
