METHOD FOR VISUALLY DETERMINING DRIFT MOBILITY IN AZIDES OF HEAVY METALS Russian patent published in 1997 - IPC

FIELD: solid-body physical chemistry; analyzing ambipolar mobility in disintegrating systems and analyzing materials for purity. SUBSTANCE: method involves exposure of crystal to ultra-violet radiation or constant electric field, or irradiation with fast electrons, followed by placing crystals in electric field with pulse length of 10-4 to 10-1s; then metal is developed in one crystal and other one is dissolved; diameter of escaping gas bubbles and offset distance from excited region are determined. EFFECT: enlarged functional capabilities. 1 tbl
