山科学院化学部和江苏省电子工业厅主持的“水浆法氢还原制备超细、微细镍粉及GNY_3镉镍电池新工艺技术鉴定会”于四月九日至四月十一日在江苏省徐州市召开。本项成果是在根据一九八五年四月由科学院化工冶金研究所与徐州无线电元件四厂签订的协议开展的扩大试验中取得的。成果共分为粉末制备新方法和电池制备新工艺两个部分。化冶所水浆法氢还原制备超细和微细粉末,工艺简单,能立足于工业废料的回收,成本较传统的电解法和羰基法低廉;生产的粉末粒度较细、形状规则、分布均匀且易于控制。为电池试制的样品完全符合所需技术要求,并已为扩大试验提供了几百公斤粉末。元件四厂用此种
Institute of Chemistry and the Jiangsu Provincial Department of Electronics Industry hosted the “water slurry method hydrogen reduction of ultrafine, fine nickel powder and GNY_3 Ni-Cd battery New Technology Identification Society ” in the April 9 to April 11 in the Xuzhou City, Jiangsu Province held. This achievement was achieved in the expansion test conducted in April 1985 in accordance with the agreement signed between the Institute of Chemical Metallurgy, Academia Sinica and the No. 4 Radio Component Factory of Xuzhou. The results are divided into a new method of preparation of powder and battery preparation of new technology in two parts. The method of hydrotreating hydrogenation of hydrometallurgy to prepare ultrafine and fine powder has the advantages of simple process, high cost and low cost compared with the traditional electrolytic method and carbonyl method. The produced powder has the advantages of small particle size, uniform shape and uniform distribution Easy to control. The prototypes for batteries were fully compliant with the required specifications and have been supplied with hundreds of kilograms of powder for extended trials. Four components used in this plant
