Preparation technology of nano bismuth oxide

For the preparation of nano bismuth oxide, the main methods include plasma method, melt spray oxidation method, chemical vapor condensation method, sol-gel method, chemical precipitation method, etc. Each method has its own characteristics. The plasma method has the advantage of short process, but requires special equipment, one-time investment, high cost; Melt spray oxidation process is short, but there are some problems such as incomplete bismuth oxidation, short nozzle life, dangerous operating environment, etc. Chemical vapor condensation method has high [...]
