WebJun 7, 2024 · Bismuth catalysts also tend to lose activity during the curing process, which often leads to poor through-cure. This deactivation is likely due to hydrolysis of the bismuth catalyst. The bismuth/zinc catalyzed system had a delayed onset point; however, the reaction rate beyond the gel point was still lacking. When red-hot, it reacts with water to make bismuth (III) oxide. [32] 2 Bi + 3 H 2 O → Bi 2 O 3 + 3 H 2 It reacts with fluorine to make bismuth (V) fluoride at 500 °C or bismuth (III) fluoride at lower temperatures (typically from Bi melts); with other halogens it yields only bismuth (III) halides.
