冶金部军工办公室于1982年12月26～28日在北京华侨饭店,对北京矿冶研究总院研制的低密度镍粉召开了技术鉴定会。该粉是采用碱式碳酸镍—水系加压氢还原工艺研制的。其过程为:碱式碳酸镍→加压氢还原→液固分离→洗涤过滤→干燥、氢烧→筛分→包装
Ministry of Metallurgical Military Office in December 1982 December 26-28 at the Overseas Chinese Hotel in Beijing, Beijing Research Institute of Mining and Metallurgy developed a low-density nickel powder technology appraisal meeting. The powder is developed using basic nickel carbonate - aqueous pressurized hydrogen reduction process. The process is: basic nickel carbonate → pressurized hydrogen reduction → liquid-solid separation → washing filtration → drying, hydrogenation → screening → packaging
