## Preparation of Iron Particles Coated with Silica A method is described for coating fine iron particles (Ο³1 m) with a uniform silica layer, produced by the hydrolysis of tetraethyl orthosilicate. The presence of a small amount of gelatin on the surface of the iron particles facilitates this proc

β¦ Synopsis
Polymer particles coated with hydroxyapatite were prepared by treating Pd0 immobilized polystyrene-co-acrylic acid particles in aqueous CaCl2 and NaH2PO2 solutions. Hydroxyapatite coating took place at neutral to alkaline pH conditions, and the homogeneous growth of the hydroxyapatite layer on the surface of polymer particles was observed at relatively low temperature (30-50 degrees C). The thickness of the hydroxyapatite layer increased with reaction time. Copyright 1999 Academic Press.

## Abstract Hydroxypapatiteβtitania hybrid films on Ti6Al4V alloys were prepared by solβgel technique by incorporating presynthesized hydroxypapatite (Ca~10~(PO~4~)~6~(OH)~2~ or HAp) powders into a titaniumβalkoxide dip coating solution. Titania network was formed by the hydrolysis and condensation
