Rare earth borates, TCr(BO (sub 3) ) (sub 2) , with dolomite structure


, : Rare earth borates, TCr(BO (sub 3) ) (sub 2) , with dolomite structure. Bulletin de la Societe Francaise de Mineralogie et de Cristallographie 91(3): 293-295

The TCr(BO (sub 3) ) (sub 2) borates, with T = Lu, Yb, Er, Y, and Dy, have the structure of dolomite which corresponds to a 1:1 relationship between the T (super 3+) and Cr (super 3+) ions on the 2(b) sites of calcite in the R3c space group. The d-spacings for the borates considered are given in tables.
