Calorimetry - AlexSys

The unique feature of this calorimeter is a large sample chamber in which one can carry out chemical reactions at high temperature. Applications include drop solution calorimetry with gas flow above the sample and/or gas bubbling through the molten solvent, direct reaction calorimetry to form alloys and compounds, aluminothermic and other oxidation-reduction reactions, gas-solid, gas-liquid, and liquid-liquid reactions. More specifically, the instrument permits the measurement of the energetics of crystalline oxides, glasses, amorphous, and nanophase and porous materials, of hydrous phases and carbonates, of metals and alloys, of semiconductors, and of carbides, nitrides and oxynitrides. The thermochemical data obtained are essential to understanding materials compatibility and reactivity in both technological and geological application,and, more fundamentally, the energetics offer insight into chemical bonding, order-disorder reactions, and phase transitions.
