【Abstract】 Ni B alloy was prepared by electrical refining in induction furnace from waste Ni Al catalyst and boron oxide. Al component in the waste catalyst was used as reduction agent for reducing B 2O 3.The analyses results show that the Ni B alloy refined by the induction furnace has lower impurity content,which can meet the need of metal rolling product and metal powder of spray coating. XRD analysis also shows that the chemical components in the alloy are Ni B and Ni 4B 3(m). The refining process,additions and viscosity of slag in the metallurgical process were also discussed.更多还原
