Hydroxyapatite is the crystalline form of Calcium phosphate, which is a natural mineral of this chemical compound. It is also called hydroxylapatite that contains two hydroxyl groups, due to which its chemical formula is Ca10(PO4)6(OH)2. Every crystal of this compound is hexagonal and it can be easily transformed into other compounds, just by replacing its hydroxyl groups with other negative radicals. Hence, it is easier to create other useful compounds of apatite group that are commonly used in scientific research in nanotechnology.
 

The pure Hydroxyapatite is white in color and it is naturally available in bones and teeth of a human body. Hence, this chemical can be used artificially for strengthening these essential body parts. Now, Hydroxyapatite powder is applied as a coating over dental and bone implants, to make them look natural and stronger. It is also used as filler in curing damaged bones and muscles during orthopedic surgeries. This chemical blends very fast in the human body and heals an injury much faster.

As Hydroxyapatite is a Calcium compound, it is widely used as an ingredient in calcium supplements that can cure the calcium deficiency in children and aged people. The manufacturers of these supplements usually derive this chemical naturally from the bones of cattle, to avoid any harmful side effect to consumers. Hence, many doctors now recommend such supplements for strengthening the bones of their patients, which do not have contamination of any other heavy metal.
 
It is now proved that Hydroxyapatite dust has many advantageous effects on the skin of infants. Therefore, many reputed cosmetic companies use this mineral for manufacturing baby powder. Moreover, they add Vitamin E, aloe vera, and cornstarch to this product that will supply adequate moisture to the skin cells, making the baby skin smoother and healthier.
 
This mineral is also used for healthy defluoridation of drinking water. It optimizes the pH balance of water and makes it rich in calcium that is healthy for people. 

Prime characteristics of natural Hydroxyapatite dust

Though pure Hydroxyapatite is found in the form of white crystals, this chemical is available in many other colors in the nature. It is derived as yellow, brown, or green rocks, due to several impurities mixed with it at that stage. Hydroxyapatite powder is also available in various shapes and sizes, which affect the applications of this chemical for various causes. It is insoluble in common media like water and alcohol. However, concentrated hydrochloric acid holds the capability of dissolving this mineral, for which it should be far away from this chemical.

Apart from these above-mentioned health benefits, this mineral has also other useful application. As Hydroxyapatite particles are present in the bones and teeth of all humans, archaeologists and paleontologists study this chemical to determine the ages of fossils that are excavated out from the ground or caves. The presence of Hydroxyapatite in the bones of other creatures also help in the similar fashion, from which scientists can find lots of useful data on these subjects. Therefore, this mineral is very helpful in several ways for mankind, which prompts scientists to conduct further research on it now.
