| Abstract Scope |
AApatites have been studied for their application as laser host materials to generate high power in the near infrared and mid-infrared wavelength region. Most of the attention was paid on Czochralski grown silicate and phosphates. It is only recently researchers have started exploring their applications for bone and teeth composites. The continuous effort is devoted to develop process to achieve bone compositions both crystalline composites and glasses for good mechanical properties, bioactivity, less degradability, and regeneration characteristics. We have prepared hard composites and have processed with both organic and inorganic flux. The approach involved low temperature processing using nano and micron sized powders of silicates and titanates for inorganics and PMMA for polymer composites. We performed detailed characterization for their chemical, thermal and radiological stability. Effect of radiation was determined using commercially available Cs137 -ray source. We observed that electrical resistivity increased due to radiation exposure on these materials. |
