Thermogravimetry (TG) and Differential Scanning Calorimetry (DSC) are commonly used techniques to study the properties of materials at different temperatures.
(a) Describe what type of information is recorded during the measurement of TG and DSC. Use following format of sentences for your answers. During the TG measurement, ........ is recorded. During the DSC measurement, ........ is recorded.
(b) Draw expected results if powder samples of Al2O3 and SiO2 are studied using TG and DSC in the temperature range of 30 - 1500 oC. Please provide brief explanations of the expected results.
(c) Which technique (TG or DSC) is more beneficial to study these materials in this temperature range? Please provide your answers for each of Al2O3 and SiO2 with explanations.
