| 摘 要： | 通过差热分析仪和激光粒度分析仪对单斜仲钨酸铵(APT)以3℃/min进行热分解的试验结果分析可以得出,如要制备细颗粒氧化钨,在0℃到131.4℃时升温速度要慢,在238.0℃到297.1℃时升温速度要快。如要制备粗粒氧化钨,则反之亦然。

| Abstract: | With DSC instrument and laser granularity analysis instrument, the result of monoclinic ammonium paratungstate (APT) at the rate of 3℃/min in argon gas turns out: the thermal decomposition rapidity of monoclinic ammonium paratungstate (APT) from 0 to 131.4 ℃is slow, and that is from 238.0℃to 297.1℃is fast, if fine tungsten oxide is prepared with monoclinic ammonium paratungstate (APT). The method is vice versa if coarse tungsten oxide is prepared monoclinic ammonium paratungstate (APT). |
