Can bismuth oxidize
WebJun 1, 2024 · As can be seen, the reduction and oxidation of bismuth oxide after five cycles can occur in an alumina crucible. However, some agglomeration was observed after 2 cycles. Importantly, this was found not to affect the reactivity of the sample, because the sample melts during each cycle, which renders any agglomeration process irrelevant.
