摘要
the invention concerns a method for the production of bismutoxid containing bi2o3 of more than 99.0 99.9 and, in particular, preferably 99,95%.-% with liquid bismuth under temporal average constant and uniform intake in heated form under pressure in a reactor by the reaction temperature to a temperature in the range of about 600 to about 700 c to be stopped, and the resulting rohoxid with a m oxidation.weiteroxidiert 99.0%, with the reaktionsluft full-term rohoxid from this filtered out and recycled in the reactor, and which, when the reactor oxide has accumulated enough, the bismutzufuhr and filteroxidru00fcckfu00fchrung is interrupted and only air eingebl asen and a residual content of metallic bismuth of not more than 0.1% oxidized stuffing, not completely, but only up to about 50%, and then fought as before work. $a the invention concerns also a method for one-stage oxidation of bismuth alloys up to a degree of oxidation of metals of greater than 90%. -%. in addition to the implementation of the above procedures devices are described.
