摘要
The aim of this work is to determine the effect of lithium or magnesium addition on the microstructure of hydroxyapatite ceramics sintered at 1200 degrees C. The samples were characterised by density measurements, scanning electron microscopy (SEM), X-ray diffraction (XRD) and Vickers microhardness. Dielectric properties, dc-conductivity and microhardness were related to the microstructures developed by the sintered materials. Furthermore, significant effects due to the presence of Li+ or Mg+2 in these ceramics were established. (C) 1999 Elsevier Science Ltd and Techna S.r.l. All rights reserved.
