PEMBUATAN PASTA DAN PEMBENTUKAN LAPISAN TIPIS HIDROKSI APATIT KARBONAT
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.
