A differential thermal analysis (DTA) is used at TU Graz in the temperature range from 400 K to 1700 K to measure melting temperatures, as well as solidus and liquidus temperatures. Similar to the DSC the temperature difference between sample and an inert reference is recorded during the heating cycle. Endothermic and exothermic changes in the sample result in peaks in the measured data plotted against temperature.Typical heating rates are 10 K/min, with argon as the ambient medium. We employ a STA 449 C Jupiter from Netzsch. Thermogravimetric measurements and investigation of corrosion processes are also possible with this device.
