摘要
以微山氟碳铈精矿为原料，研究了预处理、焙烧、淬火等工艺条件对制备稀土抛光粉性能的影响。以精矿在９００℃下焙烧３小时，在炉内自然冷却至３００℃后进行淬火制取的稀土抛光粉抛蚀量最大。用粒度仪、ＳＥＭ、ＸＲＤ等分析手段对所制得的稀土抛光粉的性能进行了表征。
The technological conditions of preparing polishes from bastnasite such as pretreating with hydrochloride acid,roasting and quenching were studied.The best technological process suggested was that the bastnasite was roasted at 900℃ for 3h,cooled to 300℃ in the furnace and then quenched.The some properties of polishes were gotten by using particle analyzer,SEM,XRD and so on,and the results can be referred in the production of polishes to some extent.
