Bayan Obo in Baotou is a large polymetallic symbiotic mine in China. In 1978, comprehensive utilization research on Bayan Obo mineral resources was listed as one of the 108 key projects and 3 major research centers in China. As deputy premier of the State Council, Fang Yi, distributed scientific and technological research to more than a 100 institutes, universities, and enterprises, The first director of the Institute of Chemical Metallurgy, Chinese Academy of Sciences (ICM CAS, now Institute of Process Engineering, IPE CAS) Yap Chu-Phay made a forward-looking and strategic suggestion on the comprehensive utilization of Bayan Obo mineral resources in the 1950s-1960s; however, it was not totally accepted by the central ministries at that time. From 1978, ICM CAS assumed the important comprehensive utilization research mission that was to extractrare earth from the blast furnace slag of Bayan Obo ore. Scientists of the ICM CAS made fruitful research achievements with pilot test successes in Baotou enterprises. This paper analyses the relationship between scientific and technological consultation and research and major national strategicneeds through studying the history of Yap Chu-Phay’s suggestion of the comprehensive utilization of rare earth and the chemical metallurgy research on Bayan Obo mineral resources comprehensive utilization. From this case study, the paper reflects how Chinese state-run research institutions such as IPE CAS conduct scientific and technological research to meet major national strategic needs.

随着我国国民经济的不断发展,对能源的需求也随之不断增长.椐统计,2000年原煤产量为9.98亿吨;原油、天然气产量分别由1990年的1.38亿吨和153亿立方米增加到2000年的1.63亿吨和270亿立方米;发电量由1990年的6212亿千瓦时上升到2000年的13500亿千瓦时,其中水电由1990年的1267亿千瓦时上升到2000年的2400亿千瓦时.核电从无到有,2000年核电发电量164亿千瓦时.

氧泵采用一种固体电解质电解槽,把氧从空气中分离出来并具有一定压力,生产高纯氧.氧泵制氧不需要庞大的机械和危险的氧压机,其生产成本可比常规空分技术降低1/3并可大幅度降低能耗.本文详细介绍了氧泵制氧技术的原理和氧泵在国内外的发展情况.

The effect of electroless plated Ni-Co-P alloy coating on the kinetic properties of Mm(NiCoAlMn)5 rare earths based hydride electrode was investigated by electrochemical techniques. The results indicate that the kinetic properties of MH electrode, including exchange current density i0, limiting current density iL, and diffusion coefficient of hydrogen in α phase Dα(H) are improved markedly. These improvements of kinetic properties lead to the increase of anodic peak current and peak integration area of MH electrode modified by Ni-Co-P alloy in CV curve as well as the decrease of overpotential of anodic and cathodic polarization.

The metallo-organic decomposition (MOD) process is a new technique with many advantages for producing inorganic films. This paper introduces the basic conditions required to satisfy metallo-organic compounds used as precursors as well as their synthesis methods. The MOD process and its applications in solid oxide fuel cells (SOFC) and in the electronic industry are highlighted.
