SYNTHESIS OF A CRYSTALLINE HYDRATED BASIC YTTERBIUM CARBONATE, YB2O3-CENTER-DOT-2.17CO(2)CENTER-DOT-6.17H(2)O

摘要

Crystalline ytterbium carbonate, Yb2O3 . 2.17CO(2) . 6.17H(2)O, was synthesized using ammonium bicarbonate as precipitant. The results of chemical analyses suggest that the ytterbium carbonate synthesized is a hydrated basic carbonate or oxycarbonate. X-ray power diffraction data are given. The IR data for this ytterbium carbonate show the presence of two different carbonate groups. There is no stable intermediate carbonate in the process of thermal decomposition of ytterbium carbonate.
