Bismuth Oxide

Bismuth oxide commonly used to produce the Dragon's eggs effect in fireworks, as a replacement of red lead, bismuth oxide is usually obtained as a byproduct of the smelting of copper and lead ores. Bismuth oxide may also be prepared by burning bismuth metal in air. However, bismuth oxide is naturally found as the mineral bismite (monoclinic) and sphaerobismoite (tetragonal, much more rare)

Supplier of Bismuth Metal

Bismuth is a heavy, brittle metal that is primarily used in low-melt alloys. Extracted as a by-product of lead, tin, silver and copper, bismuth has a low thermal conductivity and is both stable and non-toxic. These properties make the metal an ideal substitute for lead in everything from pipes and bullets to fishing weights and sprinkler triggers.

Innovations : The Metallurgy of Copper Wire

Since bismuth is extremely poisonous to electrical copper conductors (1 ppm can not be tolerated), it is imperative that the brass and copper scrap streams be completely separated from one another. A major concern facing the wire industry is the extremely high quantity of surface defects that are generated during wire drawing by abrasive or delamination wear.
