Barium amide
웹The Crystal Structure of Barium Amide, Ba(NH 2) 2. Single crystals of barium amide can be obtained by the reaction of barium metal with ammonia during long times. At − 70° C Ba … 웹Barium nitride is produced by a method in which metal barium is heated in a nitrogen stream, a method in which barium amide is thermally decomposed, a method in which barium is hydrogenated and then heated in a nitrogen stream (Patent Document 1). The barium nitride is usually about 100 mm and is obtained as a lump of 10 mm or more.
