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.
Claims35
A cement powder comprising reactive tricalcium phosphate nanoparticles and which cures to form a cement having a major X-ray diffraction peak at a value of 2θ=30.6 degrees and lacking a major peak at a value of 2θ=25.9 degrees.
A cement paste comprising a lubricating liquid which is intermixed with a cement powder that includes reactive tricalcium phosphate nanoparticles and which cures to form a cement having a major X-ray diffraction peak at a value of 2θ=30.6 degrees and lacking a major peak at a value of 2θ=25.9 degrees.
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 and which cures to form a cement having a major X-ray diffraction peak at a value of 2θ=30.6 degrees and lacking a major peak at a value of 2θ=25.9 degrees.
A method of making a cement paste containing reactive tricalcium phosphate nanoparticles, the method comprising intermixing a lubricating liquid with a cement powder that includes reactive tricalcium phosphate nanoparticles and which cures to form a cement having a major X-ray diffraction peak at a value of 2θ=30.6 degrees and lacking a major peak at a value of 2θ=25.9 degrees.
A method of binding articles together comprising:
- providing a cement paste comprising a lubricating liquid which is intermixed with a cement powder that includes reactive tricalcium phosphate nanoparticles and which cures to form a cement having a major X-ray diffraction peak at a value of 2θ=30.6 degrees and lacking a major peak at a value of 2θ=25.9 degrees;
- placing the cement paste at an interface of the articles to be bound together;
- and
- curing the cement paste to form a bond between the articles.
