| 摘 要： | 为了降低高纯氧化铋中杂质钠的含量,研究并提出用氢氧化铋制备高纯氧化铋的工艺流程,解决了高纯氧化铋中杂质钠含量偏高的问题,且可以将钠的含量控制在1.0×10-5以内。该工艺制备高纯氧化铋具有流程短,污染处理简单,成本低的特点。

| Abstract: | In order to reducing the content of irnpunty sodium in bismuth oxide,a new process to produce bismuth oxide with bismuth hydroxide was studied.This new manufacturing process could effciently produce pare high pure bismuth oxide using bismuth hydroxide,and it could make the content of sodium less than 10 ppm.This new flow had more advantages such as short technics flow,easy pollution disposal and low cost. |
