WebBismuth oxychloride is used extensively in cosmetics. Elemental or metallic forms of bismuth include pellets, rod, wire and granules for evaporation source material purposes. Bismuth oxide is available in forms including powders and dense pellets for such uses as optical coating and thin film applications. Oxides tend to be insoluble. WebBismuth vanadate is a bright yellow powder and may have a slight green tint. When used as a pigment it contains a high Chroma and excellent hiding power. In nature, bismuth vanadate can be found as the mineral pucherite, clinobisvanite, and dreyerite depending on the particular polymorph formed. Pure bismuth is a semimetal, containing a small band gap, which leads to it having a relatively high conductivity (7.7×10 S/m at 20 °C). When the bismuth is doped with antimony, the conduction band decreases in energy and the valence band increases in energy. At an antimony concentration of 4%, the two bands intersect, forming a Dirac point (which is defined as a point where the conduction and valence bands intersect). Further increases in the concentration of an… the project is put on hold
