| Abstract | Oxalic acid was chosen as the reductant to prepare superfine VO2 powders from V2O5 under high-purity N2 atmosphere. The effect of V2O5：H2C2O4 molar ratio on the VO2 purity was investigated. X-ray diffraction（XRD）, scanning electron microscopy（SEM） and ene |
| Other Abstract | 采用氧化还原法,在N2保护气氛中,通过程序控温,用草酸还原V2O5制备VO2超细粉末,重点考察原料配比对还原产物物相纯度的影响。采用X射线衍射仪（XRD）和扫描电子显微镜（SEM）及X射线能量色散谱仪（EDS）分析产物的相组成和微观形貌,通过同步热分析（STA）和原位XRD研究VO2粉体的热致可逆相变特性。结果表明：V2O5和草酸以1：1.2~1.4的摩尔比混合,可制得较纯的单斜晶系VO2超细粉末,颗粒呈近球形,平均晶粒度约为50 nm。低温为M相（单斜晶系,P21/c）,升温时可转化为R相（正方晶系,P |
