Description

The use of an hybrid pressurized electrostatic-aerodynamic levitation furnace and procedures developed by the Japan Aerospace Exploration Agency overcame the contamination problems associated with the processing of ceramics under extreme temperature conditions. This made possible property measurements over wide temperature ranges that cover the superheated as well as the supercooled states. In this study, samples of various ceramics were levitated and their densities were found as a function of temperature by extracting the area from images of a UV backlit axi-symmetric sample of known mass. In addition, the work function of each molten material was estimated using the Richardson-Dushman equation.
