摘要
讨论了一种测定钛酸锶钡粉体居里点的 DSC(Differential Scanning Calorimeter)法。在DSC 曲线的相变温区中相变终止温度对应粉体的居里点。本法具有制样简单、测试迅速的优点。还指出了草酸共沉钛酸锶钡粉体的居里点与其表观掺锶量有良好的线性关系。
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.
