Beryllium chloride is prepared by reaction of the metal with chlorine at high temperatures: [2] Be + Cl 2 → BeCl 2. BeCl 2 can also be prepared by carbothermal reduction of beryllium oxide in the presence of chlorine. [3] BeCl 2 can be prepared by treating beryllium with hydrogen chloride. Two forms of BeCl 2 are known.
Reaction with halogens. Ca + Cl 2 → CaCl 2. Anhydrous calcium chloride is a hygroscopic substance that is used as a desiccant. Exposed to air, it will absorb water vapour from the air, forming a solution. This property is known as deliquescence. Reaction with oxygen. Ca + 1/2O 2 → CaO Mg + 1/2O 2 → MgO. Reaction with sulfur. Ca + 1/8S 8 ...

Friedrich Wöhler [71] and Antoine Bussy [72] independently isolated beryllium in 1828 by the chemical reaction of metallic potassium with beryllium chloride, as follows: BeCl 2 + 2 K → 2 KCl + Be. Using an alcohol lamp, Wöhler heated alternating layers of beryllium chloride and potassium in a wired-shut platinum crucible.
Beryllium oxide (BeO), also known as beryllia, is an inorganic compound with the formula BeO. This colourless solid is an electrical insulator with a higher thermal conductivity than any other non-metal except diamond , and exceeds that of most metals. [ 12 ]

In 1828 Wöhler was the first to isolate the element beryllium in pure metallic form (also independently isolated by Antoine Bussy). [5] [14] In the same year, he became the first to isolate the element yttrium in pure metallic form. [15] He achieved these preparations by heating the anhydrous chlorides of beryllium and yttrium with potassium ...
