Vapor pressure determination by thermogravimetry
Thermochimica Acta, 2001A method for measuring the vapor pressures of a wide range of materials using a conventional thermobalance and standard sample holders is described. The equipment is calibrated using pure reference materials of known vapor pressure and exploiting the relationship between volatilization rate and vapor pressure based on the Langmuir equation for free ...

Thermogravimetry of Selected Bentonites
Energy Sources, 2002In this research the application of thermal analysis techniques (TG-DTA) to the characterization of bentonite samples is presented. The thermal behavior of 4 bentonite samples was investigated using simultaneous thermogravimetry (TG/DTG) and differential thermal analysis (DTA) techniques. It was observed that all bentonite samples exhibit 2 weight loss

Thermogravimetry of manganese dioxides
Thermochimica Acta, 1994Abstract A number of manganese dioxides have been synthesized and investigated by X-ray diffraction, electron microscopy and thermogravimetry under flowing oxygen. The TG curves show, (a) water loss, (b) release of OH-water, and (c) oxygen release.

Temperature Calibration in Thermogravimetry
1980Five magnetic materials have been tested and certified as temperature reference materials for thermogravimetry. Use of these materials will enable the relating of data from thermobalances of different designs.
