Resumo
This paper reports an optimized, simple, fast and inexpensive method for hydroxyapatite (HA)
nanoparticle synthesis. Through a multivariate statistical analysis using a factorial design with
2³ resolution, an empirical model was developed which allows control of the shape and size of
the HA nanoparticles. This model was used to synthesize HA nanoparticles with sizes between 8
and 600 nm, formed by oriented attachment growth mechanism. The structure was confirmed by
transmission electron microscopy (TEM) and scanning electron microscopy (SEM) images, which
also showed that HA nanoparticles had well-defined nanorod forms and narrow size distributions.
It was observed that the model is statistically significant and the main parameter for the growth
of crystals in the hydrothermal process was temperature.
