Abstract
The thermovoltaic detector (TVD) consists of two metal electrodes, such as aluminum and platinum, which when placed in contact with certain types of samples at elevated temperatures, spontaneously Generates a voltage that is proportional to the decomposition reaction taking place. The compounds investigated, metal salt hydrates and various ammine type coordination compounds, yield characteristic TVD curves which are related to the thermal decomposition reactions observed by other thermal analysis techniques. The TVD output voltage is of the order of 0–1V over the temperature range of 25 to 500°C. The apparatus for the technique is extremely simple, consisting mainly of a dioital multimeter with an analog voltage output (Keithley Model 160B), a X-Y plotter, and a furnace temperature programmer.
