摘要
以分析纯K2CO3和工业纯TiO2为原料,按不同摩尔配比混合配料,采用不同的反应温度和保温时间合成钛酸钾晶须,并利用SEM和X射线衍射仪对其形貌及物相进行分析。结果表明,当TiO2与K2CO3摩尔比为5.5∶l时,1200℃下保温3h炉冷,即可制备出高纯度的钛酸钾(以K2Ti6O13为主)晶须,杂质含量少。
Potassium hexatitanate whiskers were synthesized by sintering mixtures of K2CO3 and TiO2 with different molar ration at different synthesizing and holding time. The morphology and phase of the potassium hexatitanate whiskers prepared were measured by SEM and XRD respectively. Experimental results showed that potassium hexatitanate whiskers （a main phase of K2Ti6O13 ） of high purity were obtained when the molar ration of TiO2 and K2CO3 was 5.5 ： 1, and the sintering condition was at 1200 ℃ for 3 h.
