Description

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.

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.
