• What is the difference between bismuth and bismuth oxide?

  At room temperature, bismuth​ does not react with oxygen or water, but is stable in air. When heated above the melting point, it can burn and emit a light blue flame to form bismuth trioxide. Bismuth can also be combined with sulfur and halogen at red heat. Bismuth is insoluble in water.

• What is niobium telluride?

  100% environmentally stable NbTe2 metal crystal: Niobium ditelluride is metal in bulk form. Similar to molybdenum disulfide, it has a layered structure (lamellae) with weak interlayer coupling. NbTe2 exhibits metallic and superconducting behavior. The superconducting transition is performed at a volume around 1.1 K, but it is expected to be higher for thinner sheets.

• What is copper telluride?

  Copper telluride is a black crystalline powder that is stable in air at room temperature. Copper telluride is not only an important inorganic material, but also an excellent form of storage for telluride and copper resources. Cu telluride was generated by replacing Te with Cu in H2SO4 solution, resulting in the separation and considerable enrichment of telluride from many metal ions.
