FIELD: technological processes.
SUBSTANCE: invention relates to devices for growing crystals on seed using Bridgman methods, vertical zone melting, temperature gradient, as well as their modifications. Crucible consists of housing 1 and shank 2 with inoculating chamber 3, made in form of through hole in shank, closed by plug 4, having threaded connection with shank 2.
EFFECT: technical result consists in simplification of design, allowing for marking and drilling of seeding chamber from outer side of crucible, installation of seed manually, regardless of size of crucible, and also extracting crystal without detachment from seed.
