摘要
以纳米二氧化钛和碳黑为原料 ,用微波加热合成纳米碳化钛粉体。对微波合成纳米碳化钛的反应过程进行动力学研究。用X—射线衍射法表征合成粉体的合成率及颗粒大小。结果表明 ,微波合成纳米碳化钛粉体的化学反应属零级反应 ,且确定了反应动力学方程及反应的活化能。
Nano-TiC powders were synthesized by microwave heating using nano-sized materials TiO 2 and black C.The processing of microwave synthesizing nano-TiC was studied kinetically.TiC powders were characterized using X-ray diffraction(XRD).The result showed that the chemical reaction of microwave synthesizing nano-TiC is a zero level reaction,the kinetic equation of the reaction and the reaction's activation energy were confirmed.
