| Abstract: | The DSC(Differential Scanning Calorimeter)method for determiningthe Curie Point of the coprecipitating powder of Ba_(1-x)Sr_xTiO_3 is discussed.In thetemperature range of the phase change of the DSC curve,the terminal temperaturecoresponds to the Curie Point of the powder.This method has two advantages:speed determination and making simply sample.It is also pointed out that there isa excellent linear relation of Curie Points of the powders with apparent Sr-dopedquantity. |
