补充资料:X射线衍射仪
      利用计数器来收集晶体衍射方向和衍射强度数据,进行物相鉴定或晶体结构分析的仪器(图1)。有多晶X射线衍射仪和单晶四圆 X射线衍射仪。X射线衍射仪由X射线发生器、测角仪和探测记录系统等 3部分组成(图2)。其工作原理是:粉末样品经一束平行的单色 X射线垂直照射后,产生一组以入射线为轴的同轴反射圆锥面族,计数管绕样品旋转,依次测量各反射圆锥面2θ角(即衍射角,又称布喇格角)位置的衍射线强度,即可获得表征物相的各种衍射数据,从而进行物相鉴定和晶体结构的研究。  X射线衍射仪是矿物学研究领域内的主要仪器,用于对结晶物质的定性和定量分析,还可确定类质同象混晶(固溶体)的成分,有限固溶体的固溶极限,区分晶质和非晶质结构的变化。测定晶体的有序-无序结构及其有序度,以及粘土矿物的混层结构等。
