'''Bismuth silicon oxide''' is a solid inorganic compound of ], ] and ]. Its most common ] is Bi<sub>12</sub>SiO<sub>20</sub>, though other compositions are also known. It occurs naturally as the mineral ] and can be produced synthetically, by heating a mixture of bismuth and silicon oxides. Centimeter-sized single crystals of Bi<sub>12</sub>SiO<sub>20</sub> can be grown by the ] from the molten phase. They exhibit ], ], elasto-optic, ]<ref>{{Cite web|url=https://4lasers.com/en/components/crystals/photorefractive-crystals|title = Photorefractive crystals | 4Lasers}}</ref> and ] properties, and therefore have potential applications in ]s, ]s and ] recording equipment.<ref name=r2/> Bi<sub>12</sub>SiO<sub>20</sub> can be obtained as a whitish powder with band gap of approximately 3.2 eV starting from ] and silica in presence of ethyleneglycol.<ref> |
