Bismuth oxide is a light yellow powder, which turns orange when heated, turns reddish-brown when heated, and turns light yellow after cooling.
Nano-bismuth oxide Bi2O3 (VK-Bi50) is an important functional material. Nano-bismuth oxide (VK-Bi50) is widely used.
The application of bismuth oxide in catalysts mainly has three categories:
The traditional production methods of bismuth powder include water mist method, gas atomization method and ball milling method
The hazards of chloride ions in water mainly include the following four aspects:
The treatment of high-grade bismuth concentrates is mostly smelted by pyro-method reverberatory furnaces. Bismuth concentrates are mixed with reducing agent coal powder
