Methods摇 U鄄 sing barium carbonate and butyl titanate as raw materials,the sol鄄gel method was applied to prepare barium titanate films on titanium substrates,and then the quality of films prepared under different concentrations of sol and different drying mechanismswas compared. Results摇 Comparing thetwo conditions:1) 180 益 drying,380 益 heat treatment with a heatingrateof6 益/ min,and2)dryingat 120 益,300 益 heattreatmentwith aheatingrateof3 益/ min,the filmprepared under theformer condition showed large degree of cracking after annealing. Using0.3 mol/ Lbariumti鄄 tanate sol,the film prepared under the latter condi
