羟磷灰石水泥（ｈｙｄｒｏｘｙａｐａｔｉｔｅｃｅｍｅｎｔ，ＨＡＣ）由磷酸四钙［Ｃａ４（ＰＯ４）２Ｏ，ＴＴＣＰ］及磷酸氢钙（ＣａＨＰＯ４，ＤＣＰ）组成．两者用水性溶液调拌后可凝固成形，并于体内生理状态下相转形成羟磷灰石（ｈｙｄｒｏｘｙａｐａｔｉｔｅ，ＨＡ...
Hydroxyapatite cement (hydroxyapatite cement, HAC) is composed of tetracalcium phosphate [Ca4 (PO4) 2O, TTCP] and calcium hydrogen phosphate (CaHPO4, DCP). The two can be coagulated with an aqueous solution and then phase-transformed into hydroxyapatite (HA) under physiological conditions in the body.
