重晶石粗礦The process parameters of preparing nanosized titanium dioxide powders were systematically studied by electrochemical synthesis experiments at room temperature. the rutile phase and anatase phase powders were obtained in the sizes of 9. 7nm and 9. 2nm respectively, and the complete crystal powders were formed after calcined at 400 for two hours. in the process of experiments it was observed that the low current density resulted in rutile phase powders, while the addition of little amount of ions of sulfate promoted the formation of anatase phase powders
在本實驗條件下,小的電流密度有利於金紅石相的生成,而少量硫酸根離子的引入對生成銳鈦礦相粉體有利,調整電流密度大小和引入硫酸根離子的量,可以得金紅石型和銳鈦礦型的混合混體;研究無定型粉體,銳鈦礦相粉體以及金紅石型粉體隨溫度的粒徑變化情況時發現,粉體在400以前晶粒長大相對緩慢, 400以後晶粒粗化現象嚴重。
