| 摘要 |
<p>The present invention relates to ceramic precursor compositions and chemically bonded ceramic (CBC) materials, especially Ca-based, and a composite biomaterial suitable for orthopaedic applications. The CBC-system includes a binding phase (chemical cement) and additional phases with specified chemistry imparting to the biomaterial the ability of initial strength followed by interaction with the body tissue including body liquid, to form a resorbable or partly resorbable biomaterial. The ceramic precursor composition comprises at least one silicate with Ca as the main cation with a resorption rate less or equal to that of the bone in-growth rate. Said silicate will form the binding phase of the cured material. The invention also relates to implants and surface coated devices. The cured material exhibits a compressive strength exceeding 100 MPa.</p> |
