DIFFERENTIAL THERMAL ANALYSIS (DTA) OF OXIDE SYSTEMS IN AIR TO 1620C AT ATMOSPHERIC PRESSURE.
Abstract
An apparatus used to perform differential thermal analysis of oxide systems in air at atmospheric pressure to temperatures of 1620C is described. The performance of this apparatus demonstrates excellent reproducibility to within = 3C at 1560C (0.2 percent) for compounds which have been melted, resolidified and melted a second or third time. Such precision has been established partially because of: (a) the recording on the X-axis of the actual temperature of the sample; (b) precise control of a constant rate of heating or cooling of the furnace; and (c) the use of a platinum sample holder which insures that the sample and reference materials experience the same surrounding temperature at the same time.
