Furnace Design and Calibration of High-Temperature Continuous Photograph Powder X-Ray Camera.

Abstract

Several modifications are described that were made to an x-ray camera for continuous powder photographs during programmed temperature changes. The original furnace was redesigned to extend the useful temperature range of the camera. Drawings delineating the size and operation of this furnace are included. All of the methods for furnace calibration are summarized, with special emphasis on the transition melting point technique. Materials used for furnace calibration are tabulated for easy reference. The camera with the new furnace was calibrated so that more precise high temperature measurements could be made. Further work disclosed that several more desirable features are needed; and these are given in the summary.
