水硬水泥组合物和制备及使用其的方法技术

包含硅酸钙和至少一种磷酸盐化合物的水硬水泥。该磷酸盐化合物的含量足以与水泥的水化期间产生的氢氧化钙的大部分反应形成羟基磷灰石或其它钙的磷酸盐。该磷酸盐化合物优选是磷酸一钙。该水泥不但适用于生物医药／牙科而且适用于工程应用。氢氧化钙与磷酸盐反应形成与水化硅酸钙共沉淀形成纳米尺度水平上的复合物状结构的羟基磷灰石或其它磷酸钙。固化水泥中减少的氢氧化钙含量提高了其强度并降低了其ｐＨ。羟基磷灰石的含量和降低的ｐＨ使得水泥为生物活性的并且适用于医学和牙科植入物，例如用于替换骨和牙齿材料。由于其高的强度，该水泥也用于结构／工程应用。

Water cement composition and process for making and using the same

Hydraulic cement containing calcium silicate and at least one phosphate compound. The content of the phosphate compound is sufficient to react with most of the calcium hydroxide produced during hydration of the cement to form hydroxyapatite or other calcium phosphate. The phosphate compound is preferably a calcium phosphate. The cement is not only suitable for biomedicine and dentistry, but also suitable for engineering applications. Calcium hydroxide reacted with phosphate to form calcium silicate and other calcium phosphate at the nanometer scale. The reduced calcium hydroxide content in the cured cement increases its strength and lowers its pH. The amount of hydroxyapatite and the reduced pH make cement bioactive and suitable for medical and dental implants, such as replacement of bone and dental materials. Because of its high strength, the cement is also used in structural / Engineering applications.
