DEVICE FOR PRODUCTION OF ALKALI METAL VAPORS AND METHOD FOR PRODUCTION OF ALKALI METAL VAPORS

摘要

FIELD: metallurgy. SUBSTANCE: device for production of alkali metal vapors has container with working substance and formation chamber. Working substance is placed into container connected with formation chamber through channel. Formation chamber has holes for output of alkali metal vapors. Working substance is used in form of equiatomic sodium, potassium or cesium germanides which are held in vacuum for 2-4 h at temperature of 573-723 K before decomposition. To produce vapors of alkali metals the device is heated up to working temperature in the order of 873-1073 K. EFFECT: increased quantity of produced alkali metal with high purity of desired product and simplified process. 4 cl, 1 dwg, 2 tbl
