Chemistry of Beryllium (Z=4) Chemistry LibreTexts
Physical. Despite how light it is for a metal, beryllium has a very high melting point. It also has a high modulus of elasticity that is 50% greater than steel, along with a low density The name derives from the Greek word beryllos for "beryl", a gemstone in which it is found (3BeO×Al 2 O 3 ×6SiO 2 ). Beryllium was discovered by the French chemist and Beryllium Be (Element) PubChem

On the study of Cu-64 production from 18 MeV proton
In this work, we propose a novel method for Cu-64 production using secondary neutrons emitted from 18-MeV proton bombardment of primary beryllium (Be) and beryllium–titanium (Be–Ti) targets via 64Zn(n,p)64Cu nuclear reaction. The primary target thicknesses of Be and Be–Ti were varied to obtain optimum secondary neutron beryllium or other beryllium compounds at high temperatures • Skin contact with beryllium-laden dust settled on surfaces or in liquids containing beryllium OSHA’s data indicate that the highest workplace beryllium exposures are associated with primary beryllium, ceramics, composites, and alloy manufacturing and recycling, or machiningOSHA INFOSHEET TruAbrasives

Beryllium is also alloyed with nickel and with aluminum. Primary beryllium extraction plants pro- cess beryllium in all forms, from ores to intermediate commercial products to end items. In 1968, the production of beryllium in all forms totaled about 348 tons.1 The production of beryllium fluctuates widely from year to year in response to theUnited States Environmental Protection Agency Office of Water Office of Water Regulations and Standards (WH-552) Industrial Technology Division Washington, DC 20460 EPA 440/1-89-019.7 May 1989 NAI Development FIN/ Document for Effluent Limitations Guidelines and Standards for the Nonferrous Metals Manufacturing Point Source Category Volume VII Development Document for Effluent Limitations Guidelines
