Abstract:

Hydroxyapatite Ca₁₀(PO₄)₆(OH)₂ (HA) is an important material for bone and tooth implants, as its chemical composition is similar to that of bone tissue. Owing to the inferior mechanical properties of HA, significant research activity has been associated with the development of HA coatings and composites. The interest in electrophoresis for biomedical applications steins from a variety of reasons such as the possibility of deposition of stoichiometric, high purity material to a degree not easily achievable by other processing techniques and the possibility of forming coatings and bodies of complex shape^[1]. In this work, the experimental results of a study of electrophoretic deposition of HA powders, performed in isopropyl alcohol or ethanol as a suspension medium, are reported.
