What is Beryllium?
In the Periodic Table, Beryllium is the fourth element identified by the symbol “Be.” Beryllium is one-third lighter than aluminum, but it has six times the specific stiffness of steel, making it ideal for applications where weight and strength are critical. Many people are unaware of the unique physical and performance properties imparted to its end-use goods by this magnificent metal.
Pure beryllium is a metal that is both light and strong and exceedingly fragile. After lithium, beryllium is the lightest elemental metal with a density of 1.85g/cm3.In addition to its high melting point, tensile strength, and flexural rigidity, the grey-colored metal is much sought after as an alloying element. Beryllium is six times as strong as steel but weighs only a fifth of the latter’s weight.
It makes beryllium excellent for x-ray windows, neutron reflectors, and neutron moderators. Inhalation can cause berylliosis, a persistent and potentially fatal allergy illness, even though beryllium has a pleasant taste.
History of Beryllium
Beryllium is a bit new compared to the long history of metals like gold, copper, and lead. It was not until the 1920s that beryllium’s distinctive qualities and commercial value were understood. Vauquelin found beryllium by finding beryllium oxide in the mineral beryl. Because it had a pleasant taste similar to glucose, he termed it glucinium (sugar). A metallic beryllium element was first identified in 1828 by two different chemists:
Antoine Bussy of France and Friedrich Wöhler of Germany. German telephone switchboard relays were the first to utilize copper-beryllium alloys as conductive spring components. Medical x-ray windows were the first commercial application of pure beryllium, while beryllia ceramics were used to insulate radio tube electronics.
In World War II, Beryllium was used in marine diesel engines, parachute buckles, and high-precision aircraft gyroscopic navigation and targeting systems because of its corrosion resistance, strength, and lightweight. Beryllium has been found to moderate neutrons, making it a suitable material for nuclear weapons and nuclear processes.
At the same age, beryllium responded to the need for a light material with dimensional stability over wide temperature ranges, as with the advent of space flight. Beryllium is a valuable structural material for space exploration and high-tech defense applications. NASA’s Mercury capsule was shielded with a beryllium heat shield during the Mercury mission.
Throughout the United States space program and military aircraft navigation, targeting, and missile defense systems, beryllium materials were extensively utilized. The use of copper-beryllium in-vehicle electronics and mainframe computer systems became important.
Beryllium’s unique electrical and thermal qualities helped personal computers and mobile phones attain new dependability, cost, performance, and compactness.
Production of Beryllium
With its high affinity for oxygen at increased temperatures and its tendency to decompose water when its oxide coating is removed, beryllium is difficult to extract from its compounds.
Most of the time, the mineral beryl is used to extract beryllium, either sintered with an extraction agent or turned into a soluble combination for further processing and use. To Beryl, sodium fluorosilicate, and soda are heated to 770°F to make sodium fluoroberyllate, aluminum oxide, and silicon dioxide.
Make sodium fluoroberyllate, aluminum oxide, silicon dioxide, and beryl combined with sodium fluorosilicate and soda at 770 °F. Create sodium fluoroberyllate, aluminum oxide, and silicon dioxide, beryl mixed with sodium fluorosilicate and soda at 770 °F.
A solution of sodium fluoroberyllate and sodium hydroxide in water is used to precipitate beryllium hydroxide. The melt method for extracting beryllium includes grinding beryl into a fine powder and melting it to 1,650 °C.
Concentrated sulfuric acid re-heats the melt, usually producing beryllium sulfate or aluminum sulfate at 250 to 300 degrees Celsius. Aluminum and sulfur are removed from beryllium hydroxide using aqueous ammonia.

Aluminum and sulfur are removed from beryllium hydroxide using aqueous ammonia. There are two ways to make beryllium fluoride or beryllium chloride from beryllium hydroxide: sintering and melting.
Beryllium hydroxide is treated with aqueous ammonium hydrogen fluoride to produce an ammonium tetrafluoroberyllate residue, and then heated to 1000°C to make beryllium fluoride.
Finely split beryllium and the compact metal are formed by heating the fluoride to 1650 °C with magnesium in the presence of oxygen. When coupled with carbon and chlorine, beryllium chloride is formed by heating beryllium hydroxide to produce oxide. It is then electrolyzed using molten beryllium chloride.
Alloys of Beryllium
1. Copper Beryllium
When beryllium is incorporated into copper, it generates an alloy that has the best of all worlds: a combination of strength, formability, and springiness. However, copper’s electrical conductivity has been preserved to a large extent. Copper beryllium is widely sought after in aircraft, automotive, energy exploration, and telecommunications.
2. Nickel Beryllium
Nickel beryllium alloys are utilized in various mechanical and electrical springs to keep their performance at high temperatures without relaxing or deforming. It has excellent electrical conductivity, is formable, and is corrosion-resistant. Typical applications for nickel beryllium include household oven controllers, building fire detection and suppression systems, and high-temperature automotive engine and exhaust control systems.
Compounds of Beryllium
The oxidation state +2 is unique to beryllium-containing compounds. These substances don’t have any discernible hue to them. Toxic vapors from berylliosis-sensitive beryllium can cause dermatitis in those sensitive to it, yet it tastes pleasant. One-fifth of the world’s beryllium is used in the compound beryllium oxide in the United States.
Because it is a white powder, beryllium oxide can be molded into any shape. Because of its limited electrical conductivity, beryllium compound, while being a metal, is regarded as an insulator. Beryllium is a good conductor of heat; thus, it’s worth noting.
