Structural Analysis of the Inclusion in Synthetic Rutile Single Crystal

The Transparent and semi-transparent mixed inclusion is sometime found in therutile single crystal grown by flame fusion methods. Moreover, parallel stripes are shown in theinclusion. By means of XRD and SEM, (110) face of crystal with inclusion was investigated. It isshown that inclusion is polycrystal, which consists of (110) orientated small crystal grains, some of them are affected by tension stress, the others by pressure stress. On the other hand, parallel stripes in inclusion are layer-dislocation lines or crystal boundaries, which orientate [001], they are formed from cleavage along (110) face due to thermal stress.
