Beryllium is a chemical compound consisting of beryllium and carbon.

Production

Beryllium can be produced from the elements. At 900 ° C. An exothermic reaction sets in, which the reaction is heated to 1400 ° C.

Also, the reaction of beryllium oxide and carbon at a high temperature is possible.

At higher temperatures, carbon monoxide is produced.

Properties

Beryllium forms yellow cubic crystals which react slowly with water to form beryllium hydroxide and methane.

Since the resulting beryllium is amphoteric, the reaction is accelerated in the presence of alkali metal hydroxides to form soluble Beryllaten.

The result for the entire wasserkatalysierte reaction:

Fluorine, chlorine and bromine to react with beryllium in the heat to the corresponding Berylliumhalogeniden form carbon.
