Abstract
Porous calcium phosphate films could be formed on alpha-Al2O3 substrat es by spray-pyrolysis technique. The use of calcium metaphosphate as a hinder was effective to enhance the binding strength of calcium phosp hate films to substrates. The films obtained by spray-pyrolyzing the s tarting solutions were heated at a temperature between 1000 and 1400-d egrees-C for 5h. The crystalline phase of the heated films was mainly beta-calcium orthophosphate. The thickness of this film was dependent on the spraying time and the pore sizes were about 15 mum.
