Samples of nearly theoretical density are produced by post hot isostatic pressing (post‐HIP) of presintered YBa 2 Cu 3 O 7‐x using argon as the pressure medium. The hot isostatically pressed samples show improved values for critical current density at 77 K. Experimental aspects of post‐HIP are described, and microstructural development of YBa 2 Cu 3 O 7‐x during sintering and post‐HIP is discussed.
