Ceramic composites based on tialite

The ceramic composites have been synthesized using sol-gel technology. Aluminum silicate materials with low thermal expansion coefficient (TEC) such as spodumene, cordierite, mullite as well as silica were used as additives to tialite. The parameters of sintering, TEC and flexural strength of ceramic composites were determined. The impact of additives on the kinetics of tialite eutectoid decomposition at 1100°C was studied by quantitative X-ray analysis and it has been shown that cordierite and silica additives most efficiently slow down the decomposition. It has been concluded that tialite-cordierite and tialite-silica are promising composites for ceramics
