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. Read More »
Niobium metal element, atomic number 41, group VB of the periodic table, valence 2, 3, 4, 5. There are no stable isotopes. There are 49 isotopes of niobium, ranging from NB-81 to NB-113. All elements are radioactive and manufactured, except for niobium 93, which is stable and constitutes all naturally occurring elements in the Earth's crust. Read More »

On October 27, 2017, the International Agency for Research on Cancer (IARC) of the World Health Organization (WHO) released a preliminary reference for the list of carcinogens. Arsenic and inorganic arsenic compounds are included in the list of Category 1 carcinogens. Read More »
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. Read More »
Cadmium is a very toxic heavy metal, and most of its compounds are also toxic substances. Cadmium has a wide range of uses. Cadmium salts, cadmium steam lamps, pigments, smoke bombs, alloys, electroplating, welding flux, standard batteries, metallurgical deoxidizers, atomic reactors, etc., all use cadmium. Read More »
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. Read More »

At high temperatures, aluminum vapor reacts with gaseous tellurium to form gaseous molecules that exist only transiently, Al2Te2, AlTe2. Only Al2Te3 is stable at room temperature. It can be prepared by reaction of appropriate proportion of component elements at high temperature. The conditions were 1000℃ and 1H. Read More »
Manganese telluride (MnTe) is a hot material. The quasi-reluctance in Manganese telluride (MnTe) extends to very high temperatures and produces a thermoelectric potential much stronger than that generated by electron charges alone. Thermoelectric materials convert heat directly into electricity without emitting toxic gases or requiring moving parts. Read More »
