Beryllium Oxide - an overview ScienceDirect Topics

10.2.1 Beryllium Chromates. Beryllium oxide forms a number of compounds with the chromium oxides. The exact composition depends, to a great extent, on the oxidation state of the chromium ion, Cr3, 4, 5 or 6+. For the system of BeO–CrO, no compounds are known. For the trivalent Cr (III) oxide system only BeCr 2 O 4 is known.

Beryllium Oxide - an overview ScienceDirect Topics

Beryllium oxide is remarkable for high heat conductivity that ensures heat resistance. Burnt at 1800°C, beryllium oxide is virtually insoluble in acids and does not react with fused metals (uranium, iron, nickel, calcium and others). Beryllium fluoride, BeF 2, is a colorless crystalline material and very hygroscopic.

Method of making beryllium-beryllium oxide composites ...

1991-2-12  The beryllium oxide is present in the matrix at loadings of from about 10% to about 70% by volume. Higher volume fractions of beryllium oxide result in lower thermal expansion coefficients and higher thermal conductivities. It should also be appreciated that processing becomes more difficult with volume fractions of greater than about 60%.
