Development of wall-covering glass-ceramics from raw materials

Summary

The possibility of producing wall-covering glass-ceramic materials from raw materials by crystallisation of the glass  is demonstrated. Glass-ceramics based on beta-wollastonite and diopside with various ratios were designed from raw materials such as limestone and dolomite.  The phases crystallised were examined by XRD.  Thermal expansion and mechanical properties such as bending strength and microhardness for glasses and glass-ceramics were measured.   These wall coverings have an appearance similar to granite, with superior properties.  13 refs.
