摘要：

The zirconium and hafnium tetrafluoride are the initial product for the obtaining of metallic zirconium and hafnium by a method of calcium thermic reduction. The process of sublimation is used for their refining from the interstitials. For its perfection it is necessary to know what gases are evolved from fluoride at heating in the vacuum. Evolved gas from zirconium and hafnium tetrafluoride is investigated. The warming up of layer of charge at different arrangement of heaters in the retort of sublimator was calculated. The chart of vacuum pumping of sublimator was proposed.
