Bismuth silicon oxide is a solid inorganic compound of bismuth, silicon and oxygen. Its most common chemical formula is Bi₁₂SiO₂₀, though other compositions are also known. It occurs naturally as the mineral sillénite and can be produced synthetically, by heating a mixture of bismuth and silicon oxides. Centimeter-sized single crystals of Bi₁₂SiO₂₀ can be grown by the Czochralski process from the molten phase. They exhibit piezoelectric, electro-optic, elasto-optic and properties, and therefore have potential applications in spatial light modulators, acoustic delay lines and hologram recording equipment.
