METHOD FOR BALLISTIC THERMAL ANALYSIS OF ENDOTHERMIC EFFECTS IN MELT

摘要

A method for ballistic thermal analysis of endothermic effects in melt includes sample heating, its cooling, registration of the thermogram. Heating and cooling of the sample are carried out in cycles at rate per s. For the first time the sample is heated to temperature higher than melting temperature Tby , then it is cooled to temperature equal to T-(minus) . For the second and third time heating is carried out similarly to that at the first experiment. For the fourth time it is cooled till explosive crystallization takes place, with determination of pre-crystallization over-cooling of substances.
