摘要: Abstract The powder of phosphate Ca 1/4 Sr Zr 2 (PO 4 ) 3 was synthesized by sol–gel processes in the presence citric acid and ethylene glycol. Ceramic samples were prepared from this Spark Plasma Sintering (SPS), their relative densities found to be 99.5 ± 0.3% after isothermal treatment at 860 °С for 3 min. Sintered disc-shaped ceramic ( d = 10 mm, h = 4 mm) bombarded 300 K 167 MeV Xe 26+ ions with fluences ranging 6 ⋅ 10 10 1 ⋅ 10 13 ions/cm . It that exposure highest fluence (10 ion/cm led a complete amorphization irradiated layer. observed phase transition is ascribed formation amorphous latent tracks via dense electronic excitations. Postradiation heat revealed transformation metamict crystalline form took place annealing T = 200, 300, 400, 500, 600 800 °С t = 3, 13, 11, 5, 17 15 h, respectively.
