Technical Document

Brief Overview
Barium chloride is an inorganic compound which commonly exists in its dihydrated form, BaCl2(H2O)2. It is a hygroscopic compound and appears as white powder. It is toxic and imparts a yellow-green coloration to a flame. Due to its toxicity, it has limited use in industry and laboratory. It has a density of 3.097 g/cm3 and has a boiling point of 35.7oC. It is soluble in water and alcohol. It can also slightly dissolve in hydrochloric acid, nitric acid.

Manufacturing Process
It is prepared from barium sulfate (barite) in the industry through a two-step. The first step involves the addition of carbon to barite, to form barium sulfide (BaS) at an elevated temperature. After which, barium hydroxide or barium carbonate is added to give hydrated barium chloride.
