Abstract Scope |
Hydroxyapatites are important and major components of the bone and teeth of human and animals. Phosphorous and boron rich compositions provide glassy flexibility while as calcium rich compounds show crystallinity. The ionicity plays important role in regeneration and joining of bioactive materials, the study on effects of transition material is important. The processing temperature was at 700oC to investigate the grain growth and phase transition from crystalline to glassy phase. Processing at temperature higher than 700oC showed formation of faceted particles before transition from crystalline to glassy morphology and the sample turned dark black. TGA showed good stability of the samples. We determined that the dielectric constant and resistivity at different frequencies ranging 100 Hz to 100000 Hz were not affected by the bias voltage in the range of 50 mV to 1000 mV indicating that breakdown of the material did not occur for this bias range despite low resistivity. |
