Samples of nearly theoretical density are produced by post hot isostatic pressing (post-HIP) of presintered YBa{sub 2}Cu{sub 3}O{sub 7 {minus} {ital 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{sub 2}Cu{sub 3}O{sub 7 {minus} {ital x}} during sintering and post-HIP is discussed.
