Improved HyperDSC Method to Determine Specific Heat Capacity of Nanocomposites and Probe for High-Temperature Devitrification
2 Apr 2012This note describes a method to measure the change in specific heat for nanocomposites. The temperature program for the sample (and baseline) is that of heating at a very rapid rate (400 ˚C/min) to the upper temperature, then immediately cooling at the same rapid rate to a temperature sufficiently low with little or no sample decomposition.

CalorimetryCalorimetry is a technique used to determine the heat released or absorbed in a chemical reaction. Calorimeters can be categorized into bomb calorimeters, constant pressure calorimeters, differential scanning calorimeters, isothermal titration calorimeters, X-ray microcalorimeters, heat-loss calorimeters, and high-energy particle calorimeters. The choice of calorimeter depends on the application.Thermal Analysis EquipmentThermal analysis equipment is used for measuring heat flow, weight loss, dimension changes or thermomechanical properties and is important for analyzing a material’s performance and stability. Thermal analysis equipment includes differential scanning calorimeters (DSC), thermogravimetric analyzers (TGA), thermomechanical analyzers (TMA), dilatometers, thermometers, vapor sorption analyzers, boiling and melting point apparatus. Thermal analyzers can reveal properties such as melting, crystallization and glass transitions or other processes such as oxidation, decomposition, volatilization, as well as coefficients of thermal expansion and modulus.
