개요

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.

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.
