Differential thermal analysis (DTA), thermogravimetry (TG) and differential thermogravimetry (DTG) were used for this purpose. The use of these methods allowed us to determine the temperature ranges of stability, the nature of thermochemical transformations, as well as mass losses associated with dehydration, decomposition and phase transitions.20252025.opj, .jpegThermal analysis was conducted using a Derivatograph Q-1500 D (MOM, Budapest), with a steady heating rate of 5°C/min in a free air convection atmosphere. The temperature range investigated extended from room temperature up to a maximum of 1000°C. For each measurement, platinum crucibles were used, containing approximately 0.6 mg of sample material. Thermogravimetry (TG) measures mass loss as the sample is heated, while differential thermogravimetry (DTG) examines the rate of weight loss or gain during heating, cooling, or isothermal conditions, represented as the derivative of mass change with respect to temperature or time (-dm/dt). The DTG curve is the first derivative of the TG, and the peak height of the DTG curve corresponds to the rate of mass loss at any given temperature. Differential thermal analysis (DTA) assesses the temperature difference between the sample (Ts) and reference (Tr). The graph of The Ts – Tr over the programmed temperature range displays a series of peaks, indicating the temperatures at which various thermal processes occur. Relative error is 1%.
