Provided is a method for producing ceramic balls with high strength in water and functionalities such as sterilization and heavy metal removal by sintering hydroxyapatite at lower temperature than the conventional sintering temperature. The production of synthetic ceramic hydroxyapatite properties of the chemicals used to produce powders may be classified under two main headings. Hydroxyapatite hap is a biocompatible ceramic that is widely used in a number of biomedical applications and devices. Hydroxyapatite ceramics with a hierarchical surface texturing were fabricated in order to improve the adhesive bonding strength in ceramic polymer composites hap pcl used as potential implants.

The ceramic material overcomes many of the limitations of traditional crystalline hydroxyapatite that prevent its use in industrial scale applications. Cht ceramic hydroxyapatite a new dimension in chromatography of biological molecules separation mechanism the hydroxyapatite biomolecule interactions are complex. Four types of well defined periodic macro texturings were realized on a submillimeter. Cht ceramic hydroxyapatite is a spherical macroporous form of hydroxyapatite.

Ceramic material hydroxyapatite ha which recently has been successfully coated onto a metal surface using a plasma spray technique 93 122 3 16. It has been sintered at high temperatures to modify it from a crystalline to a ceramic form. The ceramic balls using hydroxyapatite are produced by the following steps of. Hydroxyapatite has been used for a variety of biomedical applications including matrices for drug release control and bone tissue engineering materials ginebra et al 2006 although the synthetic and natural ha differ in terms of physical microstructure crystal size and porosity chemical similarities to bone in both forms account for the osteoconductive potential of ha fig.

The following simplified discussion is an attempt to clarify the most significant features. Mixing hydroxyapatite hap ca10 po4 6 oh 2 preferably. The ceramic material retains the unique separation properties of crystalline hydroxyapatite and lot to lot control assures reproducibility in large scale production columns. Due the close similarity between nanometer scale forms of hap and the mineral phase found in the natural bone matrix recent.

The calcium phosphate ceramic can improve the bioactivity osteoconductivity and resorbability of composite biomaterials 1 3. Purpose of experimental studies the purpose of the present series of experimental stud ies was systematically to evaluate potential improve ments of bone implant fixation using hydroxyapatite.
