摘要: The present invention relates to chemically bonded ceramic precursor material of aluminates and silicates exhibiting a controlled release rate and properties that make the material suitable as a carrier material used in drug delivery. According to the invention, this is accomplished by selecting a microstructure based on pre-reacted phases and/or reacting phases, which contains the drugs. The present invention also relates to a cured ceramic material and a method of manufacturing said cured material. The precursor and the cured ceramic material according to the present invention can suitably be used for different types of drug intake and delivery.

摘要: 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 includes 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. The silicate will form the binding phase of the cured material. Implants and surface coated devices are also disclosed. The cured material exhibits a compressive strength exceeding 100 MPa.
