Popis:	The crystal structure of the high temperature phase of KAlSi 2 O 6 at 700 dgC has been refined to R (%) = 5.4 by the least-squares method using 309 reflections. The thermal oscillation of K atom is great and the equivalent temperature factor B eq = 15.871(27) A 2 . One of the principal axes of the thermal ellipsoids in K atom is close to the [111] direction and the magnitude of rms amplitude in this axis is larger than in other axes.
