| Abstract: | A great deal of work has been given to the synthetic process of nano crystalline thin film of perovskite structure complex oxide LaMO 3 (M=Ni 3 ,Co 3 ,Fe 3 ) by means of sol gel method using citric acid as a chelating agent.The pH value plays an important role in citric acid chelating La 3 and metal ion M.The influence of the ways in which the metal ions may be complex with citric acid is studied.It is found that good gel film benefits the formation of ceramic thin film.Lower drying rate profits the appearance of complete gel film.When pretreatment temperature accords with sintering temperature,good ceramic thin films can be prepared. |
