METHOD FOR TREATING FLUORIDES BY SUBLIMATION AND APPARATUS FOR THE WORKING THEREOF
Patent

OSTI ID:4241627
An apparatus for sublimation of fluorides is described which can be used for a variety of fluorides. The device, which is arranged to operate near 0.001 mm and up to 1000 deg C, has a condensing plate the temperature of which can be regulated by positioning a water-cooled plate at the distance corresponding to the desired temperature. Graphite plates are fixed in the apparatus with holes ~0.5 mm diam. inclined 70 deg with respect to the axis of the cylindrical vessel. The fluoride vapor acquires a helical or swirling motion as it moves upward through these holes. Thus impurities in the vapor are brought against the walls and deposited in circular or helical grooves there. (T.R.H.).
