Selenium and Tellurium Statistics and Information
In the late 1990s, the use of selenium (usually with bismuth) as an additive to plumbing brasses to meet no-lead environmental standards became important. The average price for selenium …
Coordination chemistry of homoatomic ligands of …
A rather different bonding situation accounts for heteronuclear polyhedral polycations of bismuth or antimony with tellurium or selenium , , , , . Here electron counting is based on 2c2e bonds similar to Zintl phases, although interatomic distances as well as DFT calculations suggest that in particular linear three-centre bonds also occur.
The role of selenium and tellurium in - eprints@NML
Selenium. tellurium and bismuth constitute the group of special additives which enhance the cutability of steel, each additive having its own advantages emphasized by its proponents. Such steels, however, are still only it small fraction of the total volume of "free-machining" steels made without the benefit of these special additives, because
