Nano - hydroxyapatite was synthesized by hydrothermal method in the submerged circulating impinging stream reactor, using calcium nitrate and sodium phosphate as reactants and acetamide as dispersant.
在浸没循环撞击流反应器中，以硝酸钙和磷酸钠为原料、乙酰胺为分散剂，采用水热法合成了纳米羟基磷灰石。

The elements are coprecipitated in bone in the ration of about 2 calcium: 1 phosphorus forming hydroxyapatite.
钙磷两种元素以约2∶1的比例形成羟基磷灰石沉积在骨骼内。

Calcium phosphate ceramics, such as tricalcium phosphate (TCP) and hydroxyapatite (ha) are commonly used as bone substitutes.
