Ceramat synthesizes nanocrystalline grade hydroxyapatite which can be utilized in bone repair and bone regeneration applications. Further this grade is ideal to synthesize granules, manufacturing of bone grafting material. In addition, this grade can also be employed to coat implant surface where finer surface roughness plays a significant role. It is also utilized in the manufacturing of bone filling material and scaffolds which facilitates enhanced osseointegration of bone cells.
