Influence of calcite in a ceramic body on its thermophysical properties
Original language description
We study thermal expansion, mass changes, heat capacity, and thermal diffusivity and conductivity for a ceramic body with (10 and 20 mass%) and without waste calcite content, using the TDA, TG, DTA, DSC, and flash method. The measurements were performed(a) for green samples either isothermally or by a linear heating up to a temperature 600, 1,050, or 1,100 C, depending on the measurement method; (b) at the room temperature for samples preheated at 100, 200,..., 1,100 C. In case (a) we show that a highcalcite content may double the energy consumption during the anorthite creation at 950 C. On the other hand, calcite has a slight positive effect on the final contraction and quite substantial effect on the thermal conductivity in the range 150-550 C, decreasing it even by 50 %. In case (b) a positive impact of calcite on the final contraction is about 10 times higher than in case (a). A clear effect of calcite on the thermal diffusivity occurs in case (b) only above 600 C, resulting in
