Tellurium Lump is a rare, silvery-white, semi-metallic element that exhibits both metallic and non-metallic traits. The 99.99% grade is irregular in shape and made by a physical crushing machine. While high purity grades of 99.999% and 99.99999% are made by distillation technology and shape form is like roofing tile. We can supply Tellurium lump purity range from 99.99% to 99.99999%.
