摘要
提出了用碳铵法制备高分散性微细氧化铈的新工艺,研究了碳酸铈洗涤次数,干燥和焙烧温度等因素对氧化铈的分散性能的影响,在选定的条件下,CeO_2产品的比表面积可达100～120m^2/g。
The new technology of preparing minute oxidized cerium of high dispersing properth by using ammonium carbide is discussed in this artide. The effect on the oxidized cerium' s dispersing property of such factors as washing times drying temperature and roasting temperature Under fixed circumstances the surface area of CeO2 may reach as large as 100 -120 m2/g.
