Kaolin-based glass-ceramic glaze for cordierite based high-voltage insulators Open
With the increase in the demand for electricity the improvement of the distribution system also starts to get special attention. Electricity is transferred over long distances; thus, the distribution related losses should be minimized. Con…

Young’s Modulus of Different Illitic Clays during Heating and Cooling Stage of Firing Open
Dynamical thermomechanical analysis of 5 illite-based clays from deposits in Slovakia, Estonia, Latvia, and Hungary is presented. The clays consist of illite (37–80 mass%), quartz (12–48 mass%), K-feldspar (4–13 mass%), kaolinite (0–18 mas…

Evolution of AC conductivity of wet illitic clay during drying Open
The evolution of the AC electrical conductivity during drying as well as the relationship between sample volume and moisture of green illite samples were investigated. The samples were prepared from illitic clay (80 mass % illite, 4 mass %…

Modeling of a heat capacity peak and an enthalpy jump for a paraffin-based phase-change material Open
Rubitherm RT 27 is a paraffin-based phase-change material (PCM) in which a change between a solid and liquid phase is used to store/release thermal energy. Its enthalpy and heat capacity, as measured in a quasistatic regime by adiabatic sc…

THERMOMECHANICAL ANALYSIS OF ILLITE FROM FÜZÉRRADVÁNY Open
Young’s modulus of green illite from Füzérradvány (Hungary) was measured in-situ in the temperature interval 20 °C – 1100 °C and auxiliary analyses DTA, TG and TDA, XRD and EGA, were also performed. It was found that a removal of the physi…
