The dioxide, GeO 2, can be obtained by roasting germanium disulfide (GeS 2), and is a white powder that is only slightly soluble in water but reacts with alkalis to form germanates. [36] The monoxide, germanous oxide, can be obtained by the high temperature reaction of GeO 2 with elemental Ge. [36]

The first berkelium metal sample weighing 1.7 micrograms was prepared in 1971 by the reduction of berkelium(III) fluoride with lithium vapor at 1000 °C; the fluoride was suspended on a tungsten wire above a tantalum crucible containing molten lithium. Later, metal samples weighing up to 0.5 milligrams were obtained with this method. [12] [59]
