Abstract A process for preparing low-carbon superfine REBa2Cu3O6+delta powder as the raw power of REBCO superconductor with high Jc value includes such steps as proportional mixing BaCO3 with CuO, sintering to obtain BaCuO2 powder, proportional mixing with RExOy and CuO powder and sintering at 870-920 deg.C in flowing oxygen atmosphere. Its advantages are low content of carbon, low average size less than 1 micron, and simple preparing process.
