- •
Fast, novel sol-gel synthesis of HAp nanopowders, requiring just 1 h for drying
- •
A much shortened process, 200 times faster than the usual slow drying/ageing times
- •
Compares rapidly produced HAp with that from a typical 216 h drying/ageing process
- •
Both methods produce very similar products, but rapid HAp had a larger surface area.
- •
Both methods produced pure HAp at 400 °C, and a HAp/TCP mix at 700 °C.
