摘要：
Olivine-type Co1.6SiO4 was synthesized by firing a precursor at 950 degreesC for 12 h. The precursor was obtained by the hydrothermal reaction of CoCl2 . 6H(2)O with Na2SiO3 . 9H(2)O at 150-200 degreesC for 12 h. The cell constant of Co1.6SiO4 was independent of the synthetic condition of the precursor. The specific surface area of Co1.6SiO4 was 3-4 m(2)/g. (C) 2002 Elsevier Science B.V. All rights reserved.
