Application: | Barium sulfate may be used in the following studies: • Qualitative and quantitative analysis of Ba2+ and SO4-2 ions. • Preparation of sulfur dioxide. • Preparation of hybrid organic-inorganic material. |
General description: | Barium sulphate is widely employed as an inorganic filler. Its crystals belong to the rhombic crystal system. The rhombic crystals transforms to monoclinic form at 1148°C and eventually it decomposes to barium oxide, sulfur dioxide and oxygen at temperatures above 1400°C. |
