Abstract
As described, a bioactive ceramic nanocomposite is described as follows. The composite material comprises a ceramic nanocomposite including a plurality of first grains which include calcium phosphate. The grain size may be one micron or less. The calcium phosphate may be present in the nanocomposite material in the range of 10% by weight to 70% by weight based on the total weight of the nanocomposite material. A plurality of second grains may be rapid sintered to the calcium phosphate-containing grains. The second grains may be selected from the group consisting of zirconia and alumina.
