- Group of bioceramic materials includes, among others, hydroxyapatites (HAp, OHAp, HA), which, due to their specific properties are widely applied. These compounds are currently present in bone systems of human and animal bodies. One of the solutions for improvement of poor properties of HAp is addition of zirconium oxide which is characterized by high biological tolerance and enhanced mechanical properties. Application of bioceramic materials as coatings for implants introduced into human body due to their bioinertness and biocompatibility enables overcoming immunology barriers. One of the fundamental advantages of ceramic materials is their positive impact on human tissues. The investigations involved creation of composites through single-axial compaction of two ceramic powders (HAp+YSZ) and then their sintering at the temperature of 1300oC for two hours. The aim of the investigations was to determine thermal stability of hydroxyapatite (Fig. 1) and HAp + YSZ (Partially Stabilized Zirconia) (Fig. 2) and impact of addition of YSZ (8%wt. Y2O3 stabilizing ZrO2) on phase composition of the prepared composites after the process of sintering. Investigations of the structure have been performed using JEOL JSM 5400 (Fig. 4, 5) scanning microscope while phase composition have been carried out by means of Seifert 3003 T-T X-ray diffractometer (Fig. 6, 7).
