  • 毒性 :Occupational exposures may occur in its mining, smelting, and refining. The general population ingests nickel in food. Skin sensitization and dermatitis leading to chronic eczema, called “nickel itch,” frequently occurs, especially in wearers of pierced earrings. Nickel can also irritate the conjunctiva and respiratory tract mucous membranes. Absorption from the digestive tract is poor, so systemic poisoning is rare, but since it is an irritant it acts as an emetic. Systemic effects include hyperglycemia, capillary damage, CNS depression, myocardial weakness, and kidney damage. Nickel and its compounds are carcinogenic following inhalation, but not following ingestion or skin contact. Cancer of the lung and nasal passages results, with a latent period of about 25 years; smokers are at greater risk. In addition to irritation and carcinogenesis, nickel carbonyl (nickel tetracarbonyl, Ni(CO)4) exerts relatively mild, tran_x0002_sientinitial symptoms including headache, giddiness, nausea, and shortness of breath. These symptoms are followed by very serious symptoms hours to days later, consisting of tightness in the chest, shortness of breath, rapid respiration, pulmonary edema, cyanosis, and extreme weakness; this can be fatal. Heat decomposition of nickel carbonyl yields carbon monoxide. Chelating agents can be used to remove nickel from the body.

  • 用途

    球形镍粉可用于金属3D打印，激光熔覆，表面喷涂，金刚石工具，电池正极材料，导电涂层等。

  • 制备方法 先湿法合成镍粉前躯体，然后用包覆剂均匀包覆镍粉前躯体，接着将包覆有包覆剂的镍粉前躯体用纯水洗涤3～5遍，而后在80～200℃烘干8～15小时，最后将包覆有包覆剂的镍粉前躯体依次在真空和氢气气氛下，或者依次在真空、氢气气氛和惰性气体气氛下，在400～1200℃下还原烧结1-5hr，再经洗涤去除包覆剂和其分解后的产物，最后在60-120℃烘干后即得到球形镍粉。
  • 储存 球形镍粉需密封保存于干燥、阴凉的环境中，不宜暴露空气中，防受潮发生氧化团聚，影响分散性能和使用效果。
