Hydroxyapatite powders have been made into nanosize to reduce the melting point and hence the sintering temperature. In the present investigation high energy ball mill is used to produce nanohydroxyapatite powders in bulk quantity by optimizing the milling parameters using stainless steel grinding .
Apr 15, 2019· During the process of high energy milling, a fresh reaction surface is exposed which adsorbs the gases from the air, mainly CO 2 and H 2 O . A physisorbed CO 2 could react with adsorbed water and surface hydroxyl groups to form carbonate. On the other hand, the amorphous phase also contains carbonate ions which could be a source of carbonate if ...
Here we report synthesis of nanocrystalline hydroxyapatite (HAP), a bone substitute, through dry mechanochemical method using phosphorous pentoxide and calcium hydroxide powders as starting materials, in a specially designed highenergy dualdrive planetary mill which is able to generate a strong gravitational (around 100 g) field inside the planetary mill thereby reducing the synthesis time ...
Calcific tendinitis is a form of tendinitis, a disorder characterized by deposits of hydroxyapatite (a crystalline calcium phosphate) in any tendon of the body, but most commonly in the tendons of the rotator cuff (shoulder), causing pain and condition is related to and may cause adhesive capsulitis ("frozen shoulder").. It most often occurs in females aged 30 to 60 years.
