Standard raw materials, kaolin and talc, were used in the synthesis of cordierite ceramics. The cordierite composition corresponded to 2 MgO - 2 Al₂O₃ - 5 SiO₂. Sintered cordierite was used as a refractory filler in the ceramic coating for evaporative polystyrene patterns in the new casting technology known as the Lost Foam process. Cordierite characterization was carried out by means of X-ray structure analysis. The characteristic temperatures for carrying out solid-state reactions in the three-component system of 2 MgO - 2 Al₂O₃ - 5 SiO₂ were determined differentially by thermal analysis in the range from ambient temperature to 1200°C. The obtained ceramic coatings were applied using the “full mold” casting method. For realistic evaluation of possible cordierite application in the production of evaporative pattern ceramic coatings, concurrent analyses with talc-based coatings were carried out. While cordierite has wide applications in the electrothermic, electronics, and engineering industries, it has not yet been used in casting.
