Abstract

Calcium phosphates and hydroxyapatite nanopowders have been produced by using eggshell derived raw materials and phosphoric acid at different mixing ratios. The characteristics of the end product have been found to be influenced by acid/CaO mixing ratio, milling time and heat treatment applied. Calcium phosphate foams resulted at higher acid/CaO mixing ratio with high specific surface area. Compositional analyses showed that the Ca/P atomic ratios of the calcium phosphate foams are significantly smaller than for hydroxyapatite samples. At higher sintering temperatures calcium phosphate thin and thick film coatings have been produced by a condensation method. The calcium phosphate thin films consist of micron size crystals and nanofibrous layers.
