A novel method to synthesize large-sized hydroxyapatite rods

A simple and controllable method was developed to synthesize large-sized hydroxyapatite (HAP) rods. Firstly, HAP crystals were reprecipitated from the supersaturated HAP solution in the presence of gelatin. After calcination at 600 °C for 4 h, large-sized HAP rods with good purity and crystallinity...

Summary:A simple and controllable method was developed to synthesize large-sized hydroxyapatite (HAP) rods. Firstly, HAP crystals were reprecipitated from the supersaturated HAP solution in the presence of gelatin. After calcination at 600 °C for 4 h, large-sized HAP rods with good purity and crystallinity were obtained. Furthermore, due to the protection of gelatin at a high concentration, the HAP rods had a perfect monodispersity. The average length of rod-like HAP crystals could be controlled in the range of 0.65–5 μm by simply changing the weight ratios of HAP to gelatin from 0.2:8 to 2:8.
