Research progress on preparation of nano-sized chromic oxide

Wang Xiaohua (School of Science,Chongqing Jiaotong University,Chongqing 400074,China)  
With high melting point,hardness,wear resistance,anti-corrosion,and other advantages,nano-sized chromic oxide(Cr2O3) is currently being developed and has a broad application prospect.Various preparation methods,including solid-phase methods(solid phase reaction method and mechano-chemical method),liquid-phase methods(micro-emulsion method,sol-gel method,supercritical fluid desolventizing method,radiation chemical synthesis method,hydrothermal me-thod,and deposition method),vapor-phase methods [vapor condensation method,chemical vapor deposition method(CVD),physical vapor deposition method(PVD),and laser-induced pyrolysis method],thermal spray method,and phase-transfer method of nano-sized chromic oxide were introduced.Advantages and disadvantages of those methods were briefly compared.Development trend and application prospect of nano-sized chromic oxide were described.
