Abstract

There are some archaeological bones resulting from some
archaeological excavations, and they have many different
manifestations of damage such as brittleness, fragility and weakness,
and through the aging of some samples that have been strengthened
with In this study, nano-hydroxyapatite concentrations of 1% and 2%
+ nano-paraloid concentration of 3% dissolved in acetone as an
archaeological bone-strengthening substance . Visual assessment and
several analytical techniques were used for the evaluation of the
selected strengthening material . The analytical techniques are
transmission electron microscope (TEM), color change and Pressure
strength. The results obtained from transmission electron microscope
showed that grain size of nano-hydroxyapatite with nano paraloid
was ranging from 51 to 73 nm .
