According to the origin and the solubility in the coating, Colored materials are divided into inorganic pigments and organic dyes. Since the late 18th century, Barium sulfate has been used as a white pigment in different supports, either unaccompanied or combined with other pigments. The present paper aims to review the Characteristics and application of barite. In addition to representing a brief history of this pigment, white pigments' most important physical and chemical properties have been studied. Also, all of the structural, physical, chemical, and visual properties of barium sulfate pigment, which is the main issue of this article, with the preparation, identification, and diagnosis methods, have been studied. Although this pigment was used later than the other white pigments, its production and convenience of application have expanded usage in art and industry due to its attractive properties.
