Novel Design

A high temperature solution calorimeter of a novel design has been developed whereby the separated components are brought together and mixed within a completely enclosed, vacuum-sealed cell. The instrument consists of an inner spherical compartment containing the reaction cell, surrounded by a number of concentric spherical shells made of Inconel alloy. The calorimeter may be operated at temperatures up to 1 200 °C. The temperature-sensing circuit includes a differential thermopile, a d-c. microvolt amplifier, and a recording millivoltmeter. With this instrument calorific effects of the order of 0.1 cal could be detected.

The Studies of Assumptions Accompanying the Calibration of High-Temperature Solution Calorimeter The main thesis of the research was the problem concerning calibration of high-temperature solution calorimeter with aluminum. The important assumptions applied at calibration of a device with aluminum were verified. Enthalpy values determined during the experiment clearly suggest that the level of deformation and diameters of aluminum samples used for calibration are negligible. The assumption that the temperature of the samples at the moment they reach the bath level is very close to room temperature, is appropriate.
