MATERIALS - SOLID STATE REACTIONS AT HIGH TEMPERATURE - DEVELOPMENT OF X-RAY DIFFRACTION TECHNIQUES FOR STUDY OF
Abstract
A literature survey was conducted on high temperature x-ray diffraction equipment and echniques. The designs of various cameras and diffractometers were studied and compared. After considering the advantages and disadvantages of each type, a high temperature diffractometer furnace attachment to a wide angle goniometer was decided upon. A furnace was designed which could be used to obtain x-ray diffraction paterns at temperatures up to 1600 C and at pressures of 10 to the -6th power mm of Hg or at controlled atmospheres. Essentials of this design are (1) water-cooled Al housing; (2) Al or Be foil windows for passage of x-rays; (3) water-cooled Cu electrodes; (4) Ta heating elements; and (5) Ta radiation shields. A stainless steel shaft is made to extend through the goniometer so that the furnace attachment can be interchanged with the standard room temperature sample holder with a minimum of effort. Alignment procedures and optimum sample preparations for this instrument were devised. (Author)
