Beryllium arsenide

Beryllium Arsenide is formed 6 when a mixture of beryllium and arsenic is heated the reacting mixture becomes incandescent. The arsenide is decomposed by water with evolution of arsine. 

BeSe, made by heating in melted Se is fusible, but difficultly soluble. BeTe, a grey powder. Made beryllium phosphide by heating with phosphorous and beryllium arsenide by fusing with arsenic.

Wohler (182812) thought he had prepared the selenide, telluride, arsenide and phosphide by fusing with the respective elements hut his observations have not been confirmed. Beryllium has probably never been obtained in combination with hydrogen although Winkler, (1891 3) thought he had produced a hydride. Beryllium unites directly with carbon, boron and silicon at the heat of the electric furnace (Ldieau, 1895 2, 1898 7, 1899 ii). It reduces SiCl when heated, (Rauter, 1892 2).
