Abstract
The present author and coworkers have engaged in the research and developments of inorganic phosphate materials with high performance, utilizing the characteristic properties of inorganic phosphates in the forms of crystals and glasses. The present review described our previous research regarding (i) the preparation of fibrous octacalcium phosphate (Ca8H2(PO4)6∙5H2O) and hydroxyapatite (Ca10(PO4)6(OH)2; HAp) particles due to the anisotropic crystal growth, (ii) the superplastic deformation of HAp ceramics due to the tensile force applied at high temperatures and (iii) the preparation of phosphors with variety of light emission colors (alkaline earth zirconium phosphates and alkaline earth (oxy)nitrides) and glass encapsulant (M2O-ZnO-B2O3-P2O5(-CaF2) system; M=Li and Na) for the designing of novel light emitting diodes. The present research and developments of phosphate materials in the forms of powder, sintered body and glass could be successfully conducted by the assistance of advanced preparation and analytical techniques.
