高能球磨条件下TiO2相变的实验研究
Experimental Study on Phase Transformation of TiO_2 Induced by High Energy Milling
摘要
Abstract
The mixture of TiO2 and dicyandiamide powder is processed by high energy milling at different milling speed and milling time.The structure and phase composition of the recovered samples are determined by X-ray diffraction(XRD).The results show that anatase transforms to rutile and srilankite appears at milling speed of 700 r/min.With milling time increasing,srilankite high-pressure phase content increases and gradually approaches a constant value.When the milling speed is raised to 1 000 r/min,the transformation of anatase to srilankite is dominant,and the mass fraction of srilankite high-pressure phase is increased greatly to 47.8%.关键词
