摘要

利用工业V2 O5和铝粉通过还原反应制取w（V） =96%的粗钒。在真空感应炉中

真空度高于 1.3 3× 10 -2 Pa

将电解镍与粗钒熔炼成Ni4 0 V60 合金

在 180 0～ 2 0 0 0℃精炼约 3 0min后于真空状态注入紫铜水冷锭模中

待合金锭在真空条件下凝固并冷却到 40 0℃以下时出炉

经过破碎即得到储氢材料的前驱体Ni V中间合金

Abstract

The rude V（ w （V）=96%） was prepared by reduction reaction of industrial V 2O 3 with aluminum powder.Using electrolytic nickel and rude vanadium as raw material

Ni 40 V 60 alloy is melted and refined in vacuum induction furnace with vacuum rate 1.33×10 -2 Pa at 1 800～2 000 ℃

30 min holding time and poured in water cooled copper mald.The poured ingot solidified under vacuum condition and cooled below 400 ℃ is taken out.The broken Ni V master is used for hydrogen storage material.
