Sintering of translucent and single-phase nanostructured scandia-stabilized zirconia

•Translucent scandia-stabilized zirconia pellets were produced by high-pressure SPS.•Specimens were sintered at low temperatures (700–900 °C) and high pressures (1.4–2 GPa).•The average grain size ranged from 8 to 20 nm in fully-dense ceramics.•Cubic structure was stabilized within a wide range of scandia content (6–15 mol%).
