Synthesis of cordieritic materials using raw kaolin, bauxite, serpentinite/olivinite and magnesiteSynthesis of cordieritic materials using raw kaolin, bauxite, serpentinite/olivinite and magnesite Peer-Reviewed Journal Publication Δημοσίευση σε Περιοδικό με Κριτές 2015-12-032015enIn this work it was investigated whether it is attainable to create cordieritic materials for possible uses in ceramic applications using combinations of bauxite, kaolin, serpentinite/olivinite and magnesite. For this reason various mixtures of selected samples for the synthesis of ceramic materials consisting mainly of cordierite, among other phases, were used. After appropriate processing, specimens prepared from the mixtures were fired at various temperatures up to 1350 °C. The ceramic materials resulted after firing, were investigated regarding their phases composition and physical properties of technological interest. On this way the creation of materials having interesting combinations of properties such as shrinkage (varied from 0.11% to 9.87%), porosity (varied from 0.6% to 38.5%), density (varied from 1.43 to 2.59 g/cm3), sufficient compressive strength (range of 13.1–31.0 MPa) and low coefficient of expansion (varied from 2.2 to 4.5⁎10−6/C) at high temperatures is achieved.http://creativecommons.org/licenses/by/4.0/Ceramics International4189701-9707 Kostakis Georgios Κωστακης Γεωργιος Thomaidis Efstratios Θωμαϊδης Ευστρατιος Elsevier Cordieritic material Ceramics Bauxite Kaolin Olivinite Magnesite
