Thermogravimetric Analysis Under Extreme Conditions

  Overview Thermogravimetry (TGA) is a classical method determining temperature dependent material properties. Traditional TGA is performed at ambient pressure and with relatively inert reaction gases. To measure application-relevant material properties, however, TGA must be performed under real application conditions: at high pressures, with reactive and/or corrosive gases and in steam atmospheres. The TGA and…
