Bismuth is a brittle metal with a white, silver-pink color and it’s stable in both dry and moist air at ordinary temperatures. Bismuth has a wide range of uses which take advantage of its unique properties such as it non-toxicity, low melting point, density, and appearance properties.

1. Semiconductor: Semiconductor device for high purity bismuth and tellurium, selenium, antimony and other combination, pulling the thermocouple for temperature, thermoelectric power generation and refrigeration. For assembling air conditioner and refrigerator. The optical resistance can be obtained by the use of artificial bismuth sulfide to increase the sensitivity of the visible spectral region.
2. Nuclear industry: High purity (99.999%Bi) for heat carrier or coolant for nuclear industry heap, for the protection of nuclear fission device materials
3.Other :
Additive to steel , Fusible alloys, Pharmaceutical industry
· Bismuth smelting process : feed stock ----- melting---- flow making--- precipitation---- bismuth in the bottom of the furnace----put matte----Lower the temperature and drop batches of charge
