TELLURIUM METAL POWDER
A brittle, mildly toxic, rare, silver-white lustrous metalloid which looks similar to tin. Tellurium is chemically related to selenium and sulfur. It is an easily pulverized metalloid occasionally found in native form, as elemental crystals.
Tellurium has been used to vulcanise rubber, to tint glass and ceramics, in solar cells, in rewritable CDs and DVDs and as a catalyst in oil refining. It can be doped with silver, gold, copper or tin in semiconductor applications.
Owing to the very brittle nature of tellurium powder, nanoscopic grains with an average size of 4.8 ± 0.8 nm were
produced by dry vibration milling technique using a mixer/mill apparatus. A novel material was obtained by binding the
nanosized tellurium grains with poly(methyl methacrylate) (PMMA) polymer. The morphology, elemental composition,
and structural and optical properties of Te/PMMA films were investigated. The prepared material was composed of
hexagonal tellurium and α-phase of tellurium oxide. Owing to the very brittle nature of tellurium powder, nanoscopic grains with an average size of 4.8 ± 0.8 nm were
