Abstract
A cement powder is disclosed that contains reactive tricalcium phosphate nanoparticles and other ingredients required to form a cementous material. Methods of making the reactive tricalcium phosphate nanoparticles, the cement powder, the cement paste, and cured cement are also provided, as are methods and articles for using the cement.
Claims43
A cement powder comprising reactive tricalcium phosphate nanoparticles which include sodium sulfate in an amount sufficient to prevent at least a portion of the tricalcium phosphate from forming hydroxyapatite.
A cement paste comprising a lubricating liquid which is intermixed with a cement powder that includes reactive tricalcium phosphate nanoparticles which include sodium sulfate in an amount sufficient to prevent at least a portion of the tricalcium phosphate from forming hydroxyapatite.
A biocompatible cured cement comprising the cured form of a cement paste comprising a lubricating liquid which is intermixed with a cement powder that includes reactive tricalcium phosphate nanoparticles which include sodium sulfate in an amount sufficient to prevent at least a portion of the tricalcium phosphate from forming hydroxyapatite.
A cement powder comprising reactive tricalcium phosphate nanoparticles, wherein the cement powder cures to form a biocompatible cured cement having a compressive strength that is greater than 65 MPa when intermixed with a lubricating liquid.
A cement paste comprising a lubricating liquid which is intermixed with a cement powder that includes reactive tricalcium phosphate nanoparticles, wherein the cement paste cures to form a biocompatible cured cement having a compressive strength that is greater than 65 MPa.
A biocompatible cured cement comprising the cured form of a cement paste comprising a lubricating liquid which is intermixed with a cement powder that includes reactive tricalcium phosphate nanoparticles, wherein the cement powder cures to form a biocompatible cured cement having a compressive strength that is greater than 65 MPa.
