Thermogravimetric analyses of the samples were performed on a Q-1000/D derivatograph of the F. Paulik, J. Paulik and L. Erdey system of the MOM company (). The method is based on registering changes in the thermochemical and physical parameters of a substance that can be caused when it is heated by the device. The thermochemical state of the sample is described by the curves: T (temperature), DTA (differential thermoanalytic), TG (thermogravimetric) and DTG (differential thermogravimetric). The last curve is derived from the TG function.
