from The American Heritage® Dictionary of the English Language, 4th Edition
- n. A high-melting, lightweight, corrosion-resistant, rigid, steel-gray metallic element used as an aerospace structural material, as a moderator and reflector in nuclear reactors, and in a copper alloy used for springs, electrical contacts, and nonsparking tools. Atomic number 4; atomic weight 9.0122; melting point 1,278°C; boiling point 2,970°C; specific gravity 1.848; valence 2. See Table at element.

Long-term beryllium exposure can increase the risk of developing lung cancer.
Around the plutomum is a cylinder of beryllium, which is a godsend for our purposes.
'Now, around the beryllium is a cylinder of tungsten-rhenium, which we need for its density We will purchase twelve kilograms in powder form, which we will sinter into cylindrical segments.
A potentially toxic chemical called beryllium was found in the soil and has to be removed.
While DeconGel® is gaining in use within the Department of Energy sites for remediation of radiological, nuclear, and hazardous chemical substances such as beryllium, it's also an essential product to keep on hand for hazardous materials (HAZMAT) or Chemical, Biological, Radiological and Nuclear (CBRN) first responder units concerned about immediate clean up after a major incident from accidents or acts of terrorism such as a dirty bomb.
Not surprisingly, this kind of beryllium-10 can be studied only in places with plenty of quartz, evenly distributed across the landscape.
The Blue Earth is free from harmful substances such as beryllium and phthalates, and is made out of recycled water bottles.
To find out, a team led by Jose Abreu of the Swiss Federal Institute of Aquatic Science and Technology in Duebendorf analysed 66 long-term highs from the past 10,000 years, as recorded in fluctuating levels of rare isotopes such as beryllium-10 in ice cores from Greenland.
The company's connectors are produced using materials that meet high test standards and are constructed using military-grade materials (MIL-DTL-83513 microminiature connectors and MIL-DTL-55302F connectors, including plugs and receptacles, for printed circuit subassembly), such as beryllium copper and special PPS polyphenylene sulphide fibreglass-filled thermoplastic.
Only few metals can surpass it like beryllium which is very expensive and toxic.
