| 摘 要： | 用氨沉淀铌液，如能改变沉淀条件，控制洗涤效果，调整煅烧温度，必要时加入适量的添加剂，可使原来经典法制得的Nb2O5松装密度由0．4－0．5g/cm^3提高到大于1．1g／cm^2，且Nb2O5含量大于98％，灼减值（LOI）小于1％。

| Abstract: | The bulk density of Nb2O5 can be improved from 0.4～0.5g/c.c to 1.1g/c.c,and the content of Nb2O5 to 98%,LOI be reduced down to less 1% by changing the precipitating condition,controlling of washing time and adjusting of calcination temperature,addition of a proper quantity of additive if necessary,for precipitation of Nb solution with ammonium. |
