Bismuth Strontium Calcium Copper Oxide (BSCCO) powder in the Bi2Sr2Ca2Cu3O10+x (Bi-2223) phase, the ceramic superconductor precursor behind the world’s most widely deployed first-generation high-temperature superconducting (HTS) wire. With a superconducting transition temperature near 108-110 K, Bi-2223 becomes fully superconducting well above the boiling point of liquid nitrogen, letting engineers replace costly liquid-helium cooling with a far cheaper cryogen. Our fine, tightly controlled powders are engineered for powder-in-tube processing, forming the calcined precursor packed into silver tubes and rolled into Ag-sheathed Bi-2223 tape for power cables, fault current limiters, magnets, and energy storage systems. Material is available from research quantities through bulk production volumes, with purity and particle size distribution tailored to bulk-ceramic or tape-grade requirements.
Introduction to Bismuth Strontium Calcium Copper Oxide Powder
Bismuth Strontium Calcium Copper Oxide (Bi₂Sr₂Ca₂Cu₃O₁₀₊ₓ, Bi-2223) is a layered high-temperature cuprate superconductor composed of alternating BiO and SrO blocking layers with three consecutive CuO₂ superconducting planes separated by Ca²⁺ ions. This n=3 structure produces highly anisotropic electrical properties and the highest superconducting transition temperature among the stable bismuth-based cuprates, enabling operation near liquid-nitrogen temperatures. Because bulk Bi-2223 is brittle, it is supplied as fine, phase-pure precursor powder for the powder-in-tube (PIT) process, where it is packed into silver tubes, mechanically worked, and thermally reacted to form textured multifilamentary tapes. Controlled particle size, phase purity, and stoichiometry are critical for achieving strong grain alignment and high critical current density in superconducting conductors.
Answer: Bismuth strontium calcium copper oxide (BSCCO) is primarily a high-temperature superconductor utilized in various applications, such as power transmission, MRI, magnetic levitation, etc.
Answer: Yes, its superconducting property makes it useful in electronic devices that require zero electrical resistance, such as SQUIDs and other sensitive magnetic field detectors.
Answer: BSCCO has a higher critical temperature and can be fabricated in wires and tapes, making it much more practical and valuable than traditional low-temperature superconductors.
Answer: Yes. With a Tc of roughly 108-110 K, Bi-2223 is fully superconducting when cooled with liquid nitrogen (boiling point 77 K), which is significantly cheaper and easier to handle than the liquid helium required by conventional low-temperature superconductors.
