Raw Materials | Bismuth |
White or reddish metal, metallic luster, brittle and hard. Orthorhombic system. Melting point 271 ℃; Boiling point 1420 ℃,d4 20 9.78; Broken 271 10. 07. Soluble in hot sulfuric acid, nitric acid, aqua regia, slowly soluble in hot hydrochloric acid, insoluble in water. Stable at room temperature, heating is a light blue flame and combustion, and the formation of yellow or brown bismuth oxide. The volume of molten metal increases after condensation.
high purity bismuth was obtained by melting and refining with bismuth as raw material.
It is mainly used for the preparation of compound semiconductor materials, Thermoelectric refrigeration materials, solders and liquid cooling carriers in nuclear reactors.
can cause kidney and liver poisoning, gums, cheeks, colon mucosa black spots, and bad breath, salivation, mouth surface dermatitis, skin and sticky blue bismuth line. Should be stored in a cool, ventilated, dry warehouse. The package is sealed and cannot be co-stored with inorganic acids and flammable materials. Protection against rain and sun exposure during transport.
