In this letter a relation is derived between hot isostatic pressing (HIP) temperature, the initial oxygen concentration of sintered Y-Ba-Cu-O powder, the relative density, the oxygen pressure, and the oxygen concentration during HIP densification. The maximum attainable relative density is calculated as a function of HIP pressure. It turns out that degassing oxygen during HIP densification processing has considerable effects on densification maps. Using corrected and modified densification maps a recipe for manufacturing highly dense YBa{sub 2}Cu{sub 3}O{sub 7{minus}{ital x}} is presented.
