Usage examples of erbium.
For example, for some reason we need two tons of erbium, so they run through a nifty technique to extract it from ordinary rocks.
At every stage of construction there were checkpoints: The erbium produced by this process should be 96 percent pure, with no more than a fraction of a percent impurity from the other rare earths.
As reconstructed by the Commission of Inquiry, one of the erbium dowels was sundered by an explosion.
The other three erbium dowels in the same lot were inspected and revealed no plastic explosive.
He had seen the explosion before others heard it, bad spied the several-hundred-kilogram mass of erbium arcing toward them.
Or perhaps, der Heer had gone on, sensing her displeasure, Drumlin had been thrown into the air by the concussion of the erbium hitting the staging surface.
She had, after all, been the person closest to Drumlin when the erbium dowel struck and pulped him.
Above and below she could make out the organosilicate lacework and the implanted erbium dowels, which seemed to be stirring.
She could see it glint off the black erbium cylinders, now almost stationary.
Three story overhead cranes were positioning erbium dowels in the organic matrix.
He had seen the explosion before others heard it, bad spied the several hundred kilogram mass of erbium arcing toward them.
Other elements are less familiar - hafnium, erbium, dysprosium and praseodymium, say, which we do not much bump into in everyday life.
Such stellar nuclear reactions do not readily generate erbium, hafnium, dysprosium, praseodymium or yttrium, but rather the elements we know in everyday life, elements returned to the interstellar gas, where they are swept up in a subsequent generation of cloud collapse and star and planet formation.
Each amplifier contains an approximately 10-meter-long piece of special fiber that has been doped with erbium ions, making it capable of functioning as a laser medium.
This light, directed into the doped fiber, pumps the electrons orbiting around those erbium ions up to a higher energy level.
