THE MEASUREMENT OF THE RATE OF RELEASE OF STORED ENERGY IN GRAPHITE WITH THE DIFFERENTIAL THERMAL ANALYSIS EQUIPMENT

Modifications to the original form of the differertial thermal analysis equipment have eliminated the main sources of random errors; the revined method does not require a reference sample. A change in design of the copper block has greatly simplified the assembly and reduced the magnitude of tempersture gradients in the block. An experimental correction is shown to be adequate for both thermocouple differences and the remaining tempersture gradients. Some values obtained for the rate of release of stored energy indicste that the equipment in its presert form is capable of giving results which are in fsir agreemert with those obtained on similar samples by other methods.
