Abstract
Differential scanning calorimetry (DSC) is widely-used to analyze thermodynamic material properties. However, materials that form aggressive or corrosive reaction products cannot be easily analyzed with conventional DSC devices, since they contaminate or damage these highly complex and cost-intensive apparatuses. Moreover, classical DSC devices are designed as stationary table-top units and therefore are not suitable for mobile usage. To allow for mobile DSC applications and to detect aggressive materials, the objective of our work was to develop a low-cost miniaturized all-ceramic differential scanning calorimeter device. The need of an external furnaces as it is today’s standard in table-top apparatuses should be avoided. The new device is fully manufactured using LTCC (Low Temperature Co Fired Ceramics) and thick film technology. The chip arrange-ment consists of heater and temperature sensors in a chemically inert ceramic arrangement with metallic heater and temperature sensor. This arrangement allows high reproducibility and, due to its low mass, excellent temperature control and heating rates of over 500K/min. The integrated sensor is easily replaceable and available at low cost. In the talk, the steps of the ceramic development(including finite-element modelling), the final setup, and some typical DSC-curves will be shown.
