WebThermogravimetric Analysis (TGA) What is Thermogravimetry? Thermogravimetric analysis is a method of thermal analysis in which the mass of a sample is measured over time as the temperature changes. Web6 Apr 2024 · Here, the SSA ratio between the CB and the graphite is about 30 (by argon sorption, SSA CB ∼60 m 2 /g, SSA graphite ∼2 m 2 /g, ESI Figure S2) for a burning rate ratio of about 13.5 in the first experiment conditions. In the case of TD−L conditions, the reaction rate only depends on the exposed external specific surface area (ESSA) of materials.
