Explanation
Low temperature superconductor with chemical formula Nb3Sn belongs to A15 type imermetallif compound. Cubic crystal system. Nb3Sn superconductors are brittle. Its superconductivity is very sensitive to stress and strain. Generally, Nb: lSn wire rod is made by forming first and then diffusion reaction. The preparation methods of the Nh: lSn superconducting wire rod can be divided into bronze method and white tin method. Nh: lSn superconducting materials is the same as other materials. Both critical current density and critical current decrease sharply with the increase of magnetic field. At present, Nb3Sn superconducting materials has been applied. It is mainly used for high field superconducting magnet.
