Textures In Glass Ceramics Of The System Li20-Al203-Si02

A bulk glass and a thin sol-gel film near the molar composition Li20.Al203.4Si02 were crystallised by appropriate heat treatments. Whereas the interior f the glass displayed randomly oriented spodumene crystals, the rim showed an alignment of the crystals normal to the surface. With X-ray pole figure measurements a (111) fibre texture could be confirmed. Atomic force microscope images also proved an orientation in the crystallised film and the pole fixtures confirmed a similar fibre texture as in the case of the crystalline surface layer on the bulk material.
