Process for the metallo-thermic reduction of beryllium oxide, beryllium minerals, as well as mixtures of beryllium containing metal oxides

摘要

A process for the reduction of beryllium oxide in the pure state or contained in beryllium minerals or in mixtures of metal oxides by means of finely pulverized aluminium, magnesium or silicon, with an alumino-thermic type reaction which takes place at a temperature ranging between 2400 DEG and 3200 DEG C. with the addition of compounds rich in oxygen, such as the alkali metal nitrates.
