高纯金属铽制备工艺研究

Study on Production Technology of High-purity Terbium Metal

摘要: 在SL63-7BL真空电阻炉中使用钨坩埚, 钽片做收集筒, 在真空度为10^—3pa和1750~1800℃温度下蒸馏提纯金属铽, 工艺可靠, 可以批量生产。

Abstract: The tungsten melting pot is used in SL63—7BL vacuum resistance furnace, and tantalum plate is used to gathering bulk, raw terbium metal is purified by distillation at the temperature of 1 750~1 800℃ with the vacuity of 5×l0^-3 Pa.The technology is reliable and can be batch production.
