Product Overview
Tellurium pellets are metallic-luster, silver-white crystalline forms, although they can also appear as amorphous black powder. As a non-metal element, tellurium exhibits excellent thermal and electrical conductivity, making it highly valuable in a wide range of industries. With a melting point of 452°C and a boiling point of 1390°C, tellurium demonstrates strong metallic properties. It shares chemical similarities with antimony, readily dissolving in strong acids like sulfuric acid, nitric acid, and aqua regia, but remains insoluble in both cold and hot water. Tellurium is refined to high purity through sodium polysulfide extraction.
