How can i calcute the thermal expansion co-efficient using TD/DTA - DSC analysis? Can you please help me?
DSC is not able to measue CTE. Please useThermomechanical analysis (TMA) tools
Hey Bhabu, I do use TMA to measure the CTEs of materials. I am not sure if DCS will do.
DSC can help you to find the phase transitions (melting) and the glass transition and select the interval of temperature where the material is solid. The classical TMA (Thermomechanical Analyzer) can be used to measure the "linear coefficient of thermal expansion" in solids. In isotropic and homogeneous materials the Linear coefficient of thermal expansion is 1/3 the volumetric coefficient of thermal expansion.
However, in both solid and melt state the coefficient of thermal expansione can be measured with PVT (pressure-Volume-Temperature) apparatus (please, see GNOMIX).
Respected Professors and friends, thank you for your valuable answers, I have one more doubt, Now i am working on SOFC electrolyte materials, what kind of thermal of is suitable for my research work, TG-DSC or TMA. Kindly help me
