“…The growth in hexagonal axis direction (6 3 ) seems to be favored under faster cooling rates [32–34]. Several defects were identified during the morphological analyses of the crystals such as the ‘hollow-cores’ reported by Arends and Jongebloed (Fig.…”

This work describes the synthesis of chlorapatite single crystals using the molten salt method with CaCl2 as a flux. By manipulating the processing conditions (amount of flux, firing time and temperature, and cooling rates) it is possible to manipulate the crystal morphology from microscopic fibres to large crystals (up to few millimetre long and ~100 μm thick). The crystal roughness can be controlled to achieve very flat surfaces by changing the melt composition “in situ” at high temperature. The Young modulus and hardness of the crystals are 110 ± 15 and 6.6 ± 1.5 GPa respectively as measured by nanoindentation. Crystal dissolution in Hanks solution starts around the defects. Several in vitro assays were performed; ClAp crystals with different size and shape are biocompatible. Cell apoptosis was very low at 5, 10, and 15 days (Caspase-3) for all the samples. Proliferation (MTT) showed to be influenced by surface roughness and size of the crystals.

Apatites and Their Synthetic Analogues - Synthesis, Structure, Properties and Applications

View full text Add to dashboard Cite

The previous chapters were dedicated to description of structure and properties of minerals from supergroup of apatite and introduction of method for identification and investigation of properties of phosphate minerals. The first synthesis of apatite was performed by Daubrée by passing the PCl 3 vapor over red-hot lime. The fourth chapter of this book introduces techniques for the preparation of synthetic analogs of apatite minerals including solid-state synthesis, wet chemical methods, hydrothermal synthesis as well as methods for preparation of single crystals. Chapter continues with description of structure and properties of synthetic compounds of apatite type and ends with incorporation of 3d-metal ions into the hexagonal channel of apatite.
