Bismuth oxide is produced by adding sodium hydroxide solution (free of carbon dioxide) dropwise into bismuth nitrate solution at 80-90°C. The solution is maintained alkaline during precipitation to generate white, expanded bismuth oxide hydrate Bi(OH)₃ precipitate. This solution is heated with brief stirring to dehydrate into yellow bismuth trioxide. After water decantation washing, filtration and drying, the final bismuth oxide product is obtained.
