The small ZrO2 loadings and sintering temperature used ensured that the HA did not decompose at the levels that have been observed with conventional processing routes, which require high (> 1200 °C) sintering temperatures. The formation of dense composite specimens that still retain the primary phases of hydroxyapatite and Y-TZP implies that the mechanical properties of these materials may be improved compared to HA alone 关键词: calcium compounds;ceramics;composite materials;high-temperature effects;nanostructured materials;powder technology;sintering;transmission electron microscopy;zirconium compounds;processing route;starting materials;nano sized particles;sintering temperature;dense composite specimens;primary phases;mechanical properties;high-density Ca10(PO4)6(OH)2-ZrO2 composites;1200 degC;Ca10(PO4)6(OH)2-ZrO2
