Extraction of beryllium from Indian beryl by ammonium

Sep 01, 2011A complete technological scheme for preparing high purity beryllium oxide from beryl ore using ammonium hydrofluoride has been proposed. The major advantages of this process over the conventional fluoride process of beryllium extraction are the following: (i) elimination of most of the tedious hydrometallurgical operations, (ii) virtually waste free

Beryllium oxide Wikipedia

OverviewPreparation and chemical propertiesStructureApplicationsSafetyExternal links

Beryllium oxide can be prepared by calcining (roasting) beryllium carbonate, dehydrating beryllium hydroxide, or igniting metallic beryllium: BeCO3 → BeO + CO2 Be(OH)2 → BeO + H2O 2 Be + O2 → 2 BeOIgniting beryllium in air gives a mixture of BeO and the nitride Be3N2. Unlike the oxides formed by the other Group 2 elements (alkaline earth metals), beryllium oxide is amphoteric rather than basic.

Beryllium oxide BeO PubChem

Beryllium oxide is produced by the following processes: beryllium hydroxide is first converted to high-purity beryllium sulfate tetrahydrate, as described above. This salt is calcined at carefully controlled temperatures, between 1150 and 1450 °C, selected to give the properties of the beryllium oxide powders required by individual beryllia ceramic fabricators.
