Bismuth oxide is occasionally used in dental materials to make them more opaque to X-rays than the surrounding tooth structure. In particular, bismuth (III) oxide has been used in hydraulic silicate cements (HSC), originally in "MTA" (a trade name, standing for the chemically-meaningless "mineral trioxide aggregate") from 10 to 20% by mass with a mixture of mainly di- and tri-calcium silicate powders. Such HSC is used for dental treatments such as: apicoectomy, apexification, p… WebAug 15, 2024 · Characteristic Reactions of Cadmium Ions (Cd²⁺) James P. Birk. Arizona State University.

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.
