Abstract Hydroxyapatite is a bioceramic that can be used as denture material. produced by synthesizing blood clam shells and eggshells source of calcium (NH 4 ) 2HPO , phosphate through hydrothermal methods. The hydroxyapatite samples were characterized XRD FTIR. results analysis showed the contained carbonate (CaCO 3 apatite type A. has hexagonal structure with lattice parameters = 9.404 Å c 6.675 resulting crystal size ranges from 10.19 nm to 57.29 nm. FTIR spectrum sample functional...
The Al<sub>2</sub>O<sub>3</sub> crystal has been done by Czochralki Method with different pull rate. effect of rate on the single was characterized using X-ray diffraction and density measurement. Base XRD result crystal, which belongs to hexagonal system, except for difference in relative intensity, present data are found be good agreement those powder file (PDF) 43-1484 provided JCPDS. It observed structure symmetry group...
The optical absorption spectra of single crystals titanium doped sapphire (Ti:A1203) with two different doping concentration (0.1% wt. and 0.25% wt.) have been recorded in the UV-visible spectroscopy at room temperature. It was observed that both start to show strong absorptions around 325 run. From this spectrum attempt made estimate values energy gap type transition occurs Ti:A1203o analysis it are 5.57 eV for 0.1% Ti 5.94 0.25 wt.% a direct band transition.
