摘要

Calcium phosphate [single-phase hydroxyapatite (HA), single-phase tricalcium phosphate (TCP), and biphasic HA-TCP] nanowhiskers and/or powders were produced by using a novel microwave-assisted "combustion synthesis (auto ignition)/molten salt synthesis" hybrid route. This work is an example of our "synergistic processing" philosophy combining these three technologies while taking advantage of their useful aspects. Aqueous solutions containing NaNO_3, Ca(NO_3)_2·4H_2O and KH_2PO_4 (with or without urea) were irradiated in a household microwave oven for 5 min at 600 watts of power. The as-synthesized precursors were then simply stirred in water at room temperature for 1 h to obtain the nanowhiskers or powders of the desired calcium phosphate bioceramics.
