Abstract
The manufacture of barium oxide by the action of heat on a mixture of barium carbonate and a reducing agent such as carbon, pitch, tar, or the like is carried out under reduced pressure in a rotary furnace or a furnace provided with means for agitating the reaction mixture. The furnace is preferably heated internally by electrical means, but heat may be applied instead, or in addition, from the outside. In an example, a mixture of 100 kgs. of barium carbonate and 7 kgs. of carbon is heated to 1000-1100 DEG C. under a pressure of 65-75 cms. of mercury.
