Application
It is widely used in various bismuth alloy products, low-temperature solders, metallurgy additives, and petroleum exploration.
Storage
It should be stored in a cool, ventilated, dry and clean warehouse.
Stability
It is stable at normal temperature, and burns in a light blue flame when heated, and produces yellow or brown bismuth oxide.
The volume of the molten metal increases after being condensed.
Avoid contact with oxides, halogens, acids, and interhalogen compounds.
It is insoluble in hydrochloric acid when there is no air, and it can be dissolved slowly when air is passed in.
The volume increases from liquid to solid, and the expansion rate is 3.3%.
It is brittle and easily crushed, and has poor electrical and thermal conductivity.
It can react with bromine and iodine when heated.
At room temperature, bismuth does not react with oxygen or water, and can burn to produce bismuth trioxide when heated above the melting point.
Bismuth selenide and telluride have semiconducting properties.
