beryllium Význam & definícia

Príklady beryllium

• The volcanoes we shot three months ago yielded a fine flow of lava with all sorts of metals—nickel, beryllium, vanadium, chromium, iridium, as well as copper and iron. 

• There are considerable deposits of beryllium, and they occur in high concentration in its ores. 

• We can overcoat these thermally stable mandrels with plasma polymer, vapor deposited polyimide, or sputtered beryllium with unparalleled wall thickness and composition control.

• To this end, we have designed plastic ablator capsules which are easier to fabricate and fill than beryllium capsules.

• The rapid viscosity decrease and rather small hydrogen diffusion coefficient at glass transition temperature result in "foaming" of beryllium hydride in the course of thermolysis.

• Investigation of deuterium permeability of sputtered beryllium and graded copper-doped beryllium shells.

• At this stage, a few beryllium shells with graded dopants were made but research on surface finish and characterization of the dopant levels is ongoing.

• Organic matter formed from hydrolysis of metal carbides the bombardment was converted partially into beryllium carbide, which we have discussed in the preceding paragraph.
