摘　　要：物相定性分析主要用来判定物质组成及其存在状态,是材料、化工和地质等学科专业学生必须掌握的综合性实验技能。为培养学生对材料的物相分析测试能力,设计了未知粉末物相定性分析的综合实验。以氧钼矿、黑铜矿、斜锆石和六方软锰矿的混合粉末作为盲样,依据X射线衍射和能谱元素结果,通过实验数据和综合解析推导,撰写实验分析报告,全面提高学生的仪器操作和数据分析能力。Phase qualitative analysis is mainly used to determine the material composition and its existence state,which is a comprehensive experimental skill for students majoring in Materials,Chemical Industry and Geology.The qualitative experiment of unknown powder phase was designed for cultivating students majoring in Materials.The mixed powder of tugarinovite,tenorite,baddeleyite and akhtenskite was used as an unknown sample,based on X-ray diffraction results and energy dispersive spectrum,the experimental analysis report was written via experimental data analysis and comprehensive derivation.As a result,students ability of instrument operation and instrument analysis was comprehensively improved.
