利用透射电子显微技术研究了单斜相阿利特的显微结构。选区电子衍射花样中所有的衍射斑点的位置可通过公式ha*+kb*+lc*±m(a*/6+b*/6+2c*/6)进行表达(其中:h,k,l为Miller指数;a*,b*,c*为倒易基矢;m=0,1,2或3)。结果表明:在M*型阿利特中存在着沿[112]方向的一维结构调制。调制结构可以通过高分辨透射电子显微镜进行观察,发现沿[112]方向存在着波状条纹,条纹宽度为(112)晶面间距的6倍。
The microstructure of monoclinic Alite was studied by transmission electron microscopy. The positions of all the diffraction spots in the selected area electron diffraction pattern can be expressed by the formula ha * + kb * + lc * ± m (a * / 6 + b * / 6 + 2c * / 6) Is the Miller index; a *, b *, c * is reciprocal basis; m = 0, 1, 2 or 3). The results show that there is a one-dimensional structure modulation along the [112] direction in M * type alite. The modulation structure can be observed by high-resolution transmission electron microscopy and found to have wavy stripes along the [112] direction with a stripe width of six times the (112) plane spacing.
