Bismuth Strontium Copper Oxide (Bi2Sr2CuO6), the calcium-free n=1 member of the BSCCO cuprate superconductor family, is supplied as a fine, high-purity powder for superconductivity research and precursor applications. Also known as Bi-2201, it is distinguished from its more famous calcium-bearing relatives, Bi2Sr2CaCu2O8 (Bi-2212) and Bi2Sr2Ca2Cu3O10 (Bi-2223), by a simplified single-CuO2-layer structure and a markedly lower superconducting transition temperature. Infinita Materials produces this powder under controlled stoichiometry and particle size distribution to support reactive sintering, single-crystal growth, and thin-film target fabrication. Its Ca-free chemistry makes it a valuable reference compound for isolating the intrinsic electronic behaviour of a single CuO2 plane within the broader cuprate family. Each lot is characterised for phase purity and particle size to ensure consistent, reproducible superconducting and structural properties.
Introduction to Bismuth Strontium Copper Oxide Powder
Bismuth Strontium Copper Oxide (Bi₂Sr₂CuO₆, Bi-2201) is a layered, perovskite-related cuprate consisting of alternating BiO, SrO, and single CuO₂ planes along the c-axis. As the n=1 member of the Bi₂Sr₂Caₙ₋₁CuₙO₂ₙ₊₄ series, it contains no calcium and exhibits an incommensurate structural modulation associated with excess oxygen in the BiO layers. Its single CuO₂ plane results in a relatively low superconducting transition temperature, making Bi-2201 a valuable model system for studying pseudogap behaviour, Fermi-surface topology, and fundamental cuprate physics. Supplied as a fine, homogeneous powder, Bi-2201 can be calcined and pressed into dense sputtering or PLD targets, or used as feedstock for single-crystal growth by travelling-solvent floating-zone methods.
Answer: Bismuth Strontium Copper Oxide (BSCO) is a high-temperature superconductor known for its layered perovskite structure and ability to conduct electricity without resistance at elevated temperatures.
