摘要: A crucible for melting a silica for fusion of said silica into a desired shape. The crucible having a main body with inner and outer surfaces comprised of a refractory material. In addition, the inner surface adjacent at least a melting zone of the furnace includes a substantially gas-tight barrier layer comprised of a material selected from rhenium, osmium, iridium, and mixtures thereof.
