ChemInform Abstract: Formation and Transformation of δ‐Nb2O5 Solid Solutions in the System Nb2O5‐Al2O3.

ChemInform, 1989
AbstractSolid solutions of δ‐Nb2O5 and up to 50 mol% Al2O3 are obtained by annealing amorphous materials prepared by simultaneous hydrolysis of the alkoxides Nb(OPr)5 and Al(OPr)3.

I. The binary system Nb2O5 -SiO2 ; II. The binary system CaO-Nb2O5

1962
The binary system Nb205--S102 has been shown to include an extensive two-liquid region over the range 5 to 80% Nb205. The minimum temperature of the two-liquid area is 1695°C. A eutectic composition occurs at 95% Nb205 and 1448°C. and another at approximately 5% Nb2O5 and 1695°C. The experimental results were obtained by the cone-fusion method.

The binary system ZnONb2O5

Journal of the Less Common Metals, 1972
Abstract Phase relationships in the binary system ZnONb2 O5 have been re-determined. The compounds 3ZnO.Nb2O5, α-ZnO.Nb2O5, β-ZnO.Nb2O5 and 2ZnO.17Nb2O5 have been encountered. The compounds 3ZnO.Nb2O5 and β-ZnO.Nb2O5 melt congruently at 1312 °C and 1405 °C, respectively, but 2ZnO.17Nb2O5 melts incon-gruently to liquid +H-Nb2O5 at 1415 °C and exists ...
