Document Type and Number:
WIPO Patent Application WO/2007/019795
Kind Code:
A1
Abstract:
A superconducting material, in which Cu, K/Na, Ba, Cl and O/OH are its essential components. Its molecular formula is CuAKBBaCClDOE(-OH)F or CuANaBBaCClDOE(-OH)F. And the preparing method thereof includes the following steps: grinding the admixture of CuHZ, KCl/NaCl, BaCl2, SnCl2, SnO and Sn(OH)Cl, or the admixture of CuHZ, KCl/NaCl, BaCl2, ZnCl2, ZnO and Zn(OH)Cl, or the admixture of CuHZ, KCl/NaCl, BaCl2, BaO and Ba(OH)2, or the admixture of CuHZ, KCl/NaCl, BaCl2, CaCl2, CaO and Ca(OH)2, and mixing them uniformly, and packing them, and heating them for 4-5 hours at 550 -650°C in vacuum condition, and then cooling them to the room temperature in airtight condition without air, at last airprooving and storing them to get the superconducting material.
