Abstract
FIELD: chemical industry. SUBSTANCE: claimed invention describes process for coloring natural beryl crystals and articles (jewelry inserts) for improving quality of color thereof. The claimed process comprises irradiating natural beryl crystals with ionizing radiation and heat treating thereof, subjecting heat treated crystals to secondary radiation. Primary and secondary radiations are carried out with electron beam having energy of 6-8 MeV and fluence of 10-2,5•10electron/sq.cm (during each radiation period), and heat treatment is carried out by slowly heating and cooling (2-2.4 deg/h) at 160-170 C for 1 or 2 hours. EFFECT: more efficient coloring process.
