摘　　要：通过样品的XRD谱中的水镁石和菱镁矿特征谱峰的强弱变化规律,可鉴别出煅(重)烧水镁石和轻(重)烧镁;不同的矿物有不同的物相,不同矿床的矿物物相完全相同的概率极小;同一矿床的矿物煅烧产品的XRD物相谱图不随时间发生变化,具有指纹特征。可采用粉末X射线衍射法对同一矿床生产的煅烧物进行比较。According to the change of XRD characteristic spctrum of the brucite and magnesite samples,we can distinguish the calcined brucite（or dead-burned brucite） and caustic calcined magnesite（or dead burned magnesite）. Different minerals have the different material evidence：the probability of the sameness of the material evidece of the minerals in different ore beds is seldom.The XRD characteristic spectrum of the burned products of the minerals in the same deposit can＇t change with the time going,and has the characteriatic of the fingerprint.Therefore we can compare the burned products in the same deposit through the method of the powder XRD.
