The roasting process of copper sulfide concentrate in the presence of calcium carbonate is studied by using the differentialthermalanalysis (DTA), thermogravimetric (TG) and X-ray diffraction.
Objective: To study the application of thermogravimetry (TG) and differentialthermalanalysis (DTA) in incompatibility of drugs.
目的探讨热重(TG)、差热(DTA)分析技术在药物配伍禁忌研究中的应用意义。
