性状
菱形柱状体。相对密度8.2。熔点1872℃±10℃。溶于熔融硫酸氢钾和氢氟酸，不溶于水和其他酸。
所属类别
无机化工产品: 无机盐: 其他无机化合物
用途与作用
供拉钽酸锂单晶和制造高折射低色散特种光学玻璃用，化工中可作催化剂。
合成工艺与制法
氟钽酸钾法将氟钽酸钾与硫酸加热至400℃，反应物加水至沸，经充分稀释使酸化溶液水解，生成水合氧化物沉淀，再经分离、洗涤、烘干，得五氧化二钽成品。其反应式如下：
2K2TaF7+2H2SO4+5H2O→Ta2O5+2K2SO4+14HF
金属钽氧化法将金属钽片溶于硝酸、氢氟酸混酸中，经萃取提纯，用氨水沉淀氢氧化钽，再经水洗、烘干、灼烧、磨细，得五氧化二钽成品。其反应式如下：
3Ta+5HNO3+21HF→3H2TaF7+5NO+10H2O
H2TaF7+7NH4OH→Ta(OH)5+7NH4F+2H2O
2Ta(OH)5→Ta2O5+5H2O
