• — Ceramics based on the NaRe 2 (PO 4 ) 3 phosphate with the structure of the mineral kosnarite have been prepared by spark plasma sintering. Rhenium (Re) has been used as a chemical and structural analog of technetium. The relative density of the ceramics is 85%. We have studied the mechanism of Re leaching from the NaRe 2 (PO 4 ) 3 ceramics in static mode at room temperature. The rhenium leaching rate has been determined to be 1.3 × 10 –5 g/(cm 2 day).
