Porous Cordierite Ceramics from Natural Clays
2015
Māris Rundāns, Ingunda Šperberga

In this report the obtaining and properties of high-temperature porous ceramic materials using local carbonate clays and quartz sand resources was studied. Materials with two different porosities were obtained by using different synthesis temperatures. The test results show that these materials contain cordierite as their main crystalline phase. The porosity directly influences the compressive strength and it is greatly reduced when overall porosity increases. The CTE of obtained materials is low − about 3–10−6 1/°C.
