[en] Ag-sheathed CaKFe₄As₄ superconducting tapes have been fabricated via the ex situ powder-in-tube method. X-ray diffraction analyses suggest that the CaKFe₄As₄ phase reacts strongly with the silver sheath at temperature above 500 °C. We therefore anneal the tape at 500 °C and obtain a transport critical current density J _c(4.2 K, 0 T) ∼ 2.7 × 10⁴ A cm⁻². The pinning potential derived from magnetoresistance measurements is one order of magnitude lower than that of the (Ba/Sr)_1−xK_xFe₂As₂ tapes. Combining with the scanning electron microscopy and magneto-optical imaging results, we suggest that bad connectivity between superconducting grains caused by the low sintering temperature is the main factor responsible for the low J _c. However, this system is still a promising candidate for superconducting wires and tapes if we find a compatible sheath material and further optimize the post-annealing process to achieve better grain connectivity.
