A zirconia (ZrO sub(2))-based single-phase ceramic containing simulated excess weapons plutonium waste. ZrO sub(2) has large solubility for other metallic oxides was synthesized. It was shown that significant amounts of gadolinium (neutron absorber) and yttrium (additional stabilizer of the cubic modification) can be dissolved in ZrO sub(2), together with plutonium (simulated by Ce super(4+), U super(4+) or Th super(4+)) and impurities (e.g., Ca, Mg, Fe, Si).
