    Abstract: Bismuth manganese oxide pigments are used as additives to various materials such as plastics, plastic or organic coating compositions, glass and ceramic coating compositions, and the like. The bismuth manganese oxide pigments preferably comprise Bi2Mn4O10 crystallized in the orthorhombic crystal structure. The pigments possess improved reflectance characteristics, particularly in the IR region, and may reduce IR-induced heat buildup.
