Abstract

Ceramic samples are obtained by sintering nanosized powders of La_{1 −}_xDy_xPO₄ at 1000–1600°C, and their microhardness is measured depending on the temperature and time of the thermal treatment. The thermal behavior of the ceramic samples is studied via dilatometry. The leaching resistance of the ceramic La_{1 −}_xDy_xPO₄ matrices in the contact solutions of a mixture of NaCl and Na₂SO₄ salts at room temperature is determined.
