PREPARATION OF BERYLLIUM OXIDE OF HIGH PURITY
Patent
·
OSTI ID:4062540
A process is given for the preparation of beryllium oxide of high purity. A beryllium compound selected from the group consisting of beryllium oxide, beryllium hydroxide, beryllium sulfate, beryllium carbonate, and beryllium nitrate is reacted with molten oxalic acid to produce beryllium oxalate trom the associated impurities, filtering said leach solution to separate it from unreacted beryllium compound and the more insoluble oxalates, cooling the leach solution to crystallize the beryllium oxalate, requently conventing the beryllium oxalate to beryllium oxide by pyrolysis.
