Abstract
AbstractA high-temperature high-vacuum X-ray diffractometer attachment was constructed to observe formation of materials at elevated temperatures. The device consists of a conventional water-cooled compartment, a resistance-type furnace for heating samples to 800°C, and inlets and outlets for gaseous reactants and evacuation. Two sources are available for evaporation of materials which may react with or coat the sample. The sample is aligned by a two-part sample-slit system. The sample temperature is regulated by means of a current-adjusting control unit and a self-saturating reactor with suitably positioned thermocouples. Temperature distribution and constancy over the sample surface were determined.
