| Summary: | Hydroxylapatite is one of the main components of bone tissue. In combination with collagen, it provides unique strength properties of the bone. The nanostructure of bone tissue (its composition) remains a matter of debate. In this work, we studied the cortical bone tissue of rats using transmission electron microscopy (TEM) and X-ray diffraction. According to the results of the Scherrer method, the size of hydroxylapatite crystallites is 8.8 × 4.0 nm. The TEM showed the presence of crystalline hydroxyapatite areas in the interfibrillary space of collagen with the sizes ranging from 10 × 5 to 50 × 10 nm. These areas are the crystalline aggregates with a subblock structure, which is expressed in different orientations of axis c. No amorphous substance in bone tissue was identified using electron nanodiffraction. |
