    Product Description

    Bismuth is a silvery white to light yellow lustrous metal, hard and brittle, easy to crush, with cold expansion and shrinkage characteristics. At room temperature, bismuth does not react with oxygen or water, is stable in the air, and has poor electrical and thermal conductivity. Bismuth is heated to above the melting point and burns, with a light blue flame, producing bismuth trioxide, and red bismuth can also be compounded with sulfur and halogen.
