[en] Consolidation of high temperature materials to full density by press and sinter methods is limited to relatively simple shapes. Powder injection molding (PIM) allows complex shapes to be formed but presents problems with sintering to full density. Using hot isostatic pressing with PIM would allow complex geometry to approach full density or even achieve full density. Previous investigations with Y2O3 powders using PIM forming techniques and conventional sintering resulted in densities of 92--96% of theoretical. Containerless HIP'ing sintered samples increased density to 99% of theoretical. HIP densification of debound PIM samples would eliminate high temperature sintering to close the surface porosity to allow containerless HIP'ing. This investigation explores methods of canning and HIP'ing debound PIM samples of Y23
