Strong lightweight refractory materials were obtained with an apparent density ranging from 1060 to 1280 kg/m³ based on clay and nonplastic aluminosilicate raw materials with the introduction of a low-temperature burn-out additive of expanded polystyrene (EPS). The average pore size of the ceramics is 0.05 – 0.35 mm. The optimal fractional composition of the charge and the content of EPS were determined. Physical and technical properties of these ceramic samples fired at 1300 – 1350°C were studied.
