Technology Process of BISMUTH TETROXIDE

There total 24 articles about BISMUTH TETROXIDE which guide to synthetic route it. The literature collected by LookChem mainly comes from the sharing of users and the free literature resources found by Internet computing technology. We keep the original model of the professional version of literature to make it easier and faster for users to retrieve and use. At the same time, we analyze and calculate the most feasible synthesis route with the highest yield for your reference as below:

synthetic route:

Reference yield:

bismuth hydroxide → bismuth oxide (12048-50-9,171869-78-6) + bismuth(III) oxide (1304-76-3)

Guidance literature:

With chlorine; In potassium hydroxide; inlet of Cl2 into a suspension of Bi(OH)3 in boiling KOH gives mixture of Bi2O3 and Bi2O4 (not separarted);; content of Bi2O4 increases with increasing density of alkali soln. and excess related to Bi2O3 {3};;

Reference yield:

Bi2O5*H2O → bismuth oxide (12048-50-9,171869-78-6) + bismuth(III) oxide (1304-76-3)

Guidance literature:

In neat (no solvent); fast decompn. at 100 °C;;

Reference yield:

calcium sulfate + sodium bismuthate(V) dihydrate → bismuth oxide (12048-50-9,171869-78-6) + Ca3Bi8O5

Guidance literature:

With sodium hydroxide; In water; at 120 ℃; for 24.5h; pH=9; pH-value; Autoclave;
