背景技术Background technique
镍盐是重要的化工原料。例如,硫酸镍(NiSO4)作为一种重要的化工原料,广泛地应用于电镀、电池、印染、医药、建筑、国防等领域;氯化镍(NiCl2)应用于镀镍、制隐显药水及做氨吸收剂等方面。硫酸镍和氯化镍的制备方法主要有化学法和电化学法。硫酸镍和氯化镍的传统生产原料包括电镍、高冰镍、含镍的废旧物质以及粗氢氧化镍。镍的氧化物有氧化亚镍(NiO)、四氧化三镍(Ni3O4)及三氧化二镍(Ni2O3)三种形态。三氧化二镍仅在低温时稳定,加热至400~500℃,即离解为四氧化三镍,进一步提高温度最终变为氧化亚镍,在镍氧化物中镍的质量分数可高达78.5%。但是,鲜有以镍氧化物直接制备硫酸镍和氯化镍的文献和专利报道。Nickel salt is an important chemical raw material. For example, nickel sulfate (NiSO 4 ), as an important chemical raw material, is widely used in electroplating, batteries, printing and dyeing, medicine, construction, national defense and other fields; nickel chloride (NiCl 2 ) is used in nickel plating, making invisible liquid And do ammonia absorbent, etc. The preparation methods of nickel sulfate and nickel chloride mainly include chemical method and electrochemical method. The traditional raw materials for the production of nickel sulfate and nickel chloride include electronic nickel, high nickel matte, nickel-containing waste materials and crude nickel hydroxide. Nickel oxide has three forms of nickel suboxide (NiO), nickel trioxide (Ni 3 O 4 ) and nickel trioxide (Ni 2 O 3 ). Nickel trioxide is only stable at low temperature. When heated to 400~500°C, it dissociates into nickel trioxide, and further increases the temperature to finally become nickelous oxide. The mass fraction of nickel in nickel oxide can be as high as 78.5%. However, there are few literature and patent reports on the direct preparation of nickel sulfate and nickel chloride with nickel oxide.
