Abstract

 

ABSTRACT
Paste of Carbonated Hydroxyapatite (CHA) as a biocompatible material that can be used in the
bone and teeth repair has been developed on preparation of thick film. CHA paste was prepared
by mixing precipitate of CHA with CaSO4 and polyethylene glycol (PEG) in 2-propanol as
solvent. Paste was deposited on substrate to get thick films by screen printing method. X ray
diffraction (XRD) analysis has shown hexagonal crystal structure and crystal size of CHA
acquired 7,2 nm by Scherrer’s method. Fourier Transform Infrared (FTIR) analysis has shown
absorption spectra which indicating phosphate, carbonate, and hydroxide group. Size of this
composite particles analyzed by PSA (particle size analyzer) about 3μm and pore size was 0.44-
0.49 nm obtained from BET analysis, increased with the addition of CaSO4 (0.44 to 0,49 nm).
Rephrase PEG was found as an adhesive and homogenize paste on substrat surface. In addition,
CHA paste also potentially can be used as bone cement.
Keywords : Paste, thick film, carbonated hydroxyapatite
