Abstract

Ternary systems CuO-M2O3-TO2 with T = Si, Ge and M3+ = Al, Ga, Fe, Cr, Bi and Y were investigated at 1000°C. Ternary compounds were found only for M3+ = Y. CuY2Ge2O8 is monoclinic with a = 9.477 Å, b = 15.005 Å, c = 8.030 Å and β = 147.50°; CuY2 Si4 O12 is monoclinic with a = 7.052 Å, b = 14.283 Å, c = 4.738 Å and β = 103.32°; CuY2Ge4O12 is triclinic with a = 7.185 Å, b = 7.949 Å, c = 4.910 Å, α = 86.83°, β = 102.70° and γ = 113.84°. The last two structures are closely related. The binary double oxide series Cu2Ln2O5 was reinvestigated.
