Studies of Beryllium Chromite and Other Beryllia Compounds With R(2)O(3) Oxides

Reactions between BeO and R(2)O(3) oxides at high temperatures were studied. Compound formation was observed between BeO and the following oxides: B(2)O(3), Al(2)O(3), Ga(2)O(3), Y(2)O(3), La(2)O(3), and Cr(2)O(3). No reaction was observed with Sc(2)O(3), ln(2)O(3), and Fe(2)O(3). Detailed studies w...

Sumario:Reactions between BeO and R(2)O(3) oxides at high temperatures were studied. Compound formation was observed between BeO and the following oxides: B(2)O(3), Al(2)O(3), Ga(2)O(3), Y(2)O(3), La(2)O(3), and Cr(2)O(3). No reaction was observed with Sc(2)O(3), ln(2)O(3), and Fe(2)O(3). Detailed studies were made of BeO·Cr(2)O(3) which is isostructural with BeO·Al(2)O(3). BeO·Cr(2)O(3) is a semiconductor. Optical and X-ray data are given for all reaction products.
