bismuth oxide abstract

Apr 05, 2018· 1. Introduction. Bismuth oxide (Bi 2 O 3) is not stable at the range of high temperature.Especially, while α and δ forms of Bi 2 O 3 have stable low and high temperatures, respectively; β, γ and ω forms of Bi 2 O 3 have metastable structures [,, ].This metastable disadvantage can be coped with the addition of dopants such as holmium, calcium, lanthanum and praseodymium …

A series of new "magic number" metal oxide clusters are described for the group V metals antimony and bismuth. Specific nonstatistical stoichiometries of MxOy cation and anion clusters are formed preferentially in the gas phase when oxidized metal is vaporized or when metal is vaporized and combined with gas phase oxygen (e.g., Bi7O10+, Bi9O14+).

Bismuth(III) oxide is perhaps the most industrially important compound of bismuth.It is also a common starting point for bismuth chemistry. It is found naturally as the mineral bismite (monoclinic) and sphaerobismoite (tetragonal, much more rare), but it is usually obtained as a by-product of the smelting of copper and lead ores. Bismuth trioxide is commonly used to produce the "Dragon's eggs ...
