TI  - Microstructure and Mechanical Properties of Composites of BovineDerived Hydroxyapatite (BHA) Reinforced with MgF2
AB  - Composites of calcinated bovine bone derived hydroxyapatite (BHA) doped 1 and 2 wt% MgF2 were prepared by a sintering process. Microstructure and crystallographic analyses along with measurements of density, compression strength, and microhardness were carried out in the produced samples. The experimental results indicated a beneficial effect of MgF2 in the matrix of BHA reflected in the significant increase of compression strength and microhardness up to 143 MPa and 313 HV, respectively, achieved after sintering at 1300 0C for 2% MgF2 addition. The presence of MgF2 reduced the onset of sintering towards lower temperatures (i.e. 1100 0C) and increased the stability of hydroxyapatite towards transformation to TCP at 1300 0C. The influence of Mg2+ and Fions in the lattice of hydroxyapatite is discussed.
