对制备高松装密度氧化铌工艺进行了研究。结果表明 :采用我厂未经任何特殊处理的普通萃取泥液所制的Nb(OH) 5或Nb2 O5为原料 ,通过整形、高温凝聚和筛分等工艺过程 ,制出的氧化铌的松装密度可达 1 1g/cm3以上。
The preparation of high bulk density niobium oxide process was studied. The results show that: Nb (OH) 5 or Nb2 O5 made by ordinary extraction mud without any special treatment in our factory is used as raw material. Through the process of shaping, high temperature aggregation and screening, the niobium oxide Density up to 1 1g / cm3 above.
