  • Publication number: 20130309214
    Abstract: A method of producing an injectable calcium phosphate paste by a process in which calcium phosphate precursors are mixed with the setting fluids to form a self-hardened apatite cement is disclosed. The produced apatite cement is biocompatible, bioactive and biodegradable in the body. The pH value of said apatite cement is approximately 7 with compressive strength between 10-30 MPa and the setting process will not generate.temperature >37° C. The self-hardened apatite (SHA) cement is found to be bioresorbable and can be used for bone fillers, fixation of broken bones or artificial joints in human and also appropriate for use as a delivery vehicle.

  • Patent number: 6150437
    Abstract: Flow improving agents for binder suspensions containing cement are described, which consist of:a) Graft polymers which have been prepared by radical grafting of a polyalkylene oxide of the general formula (I) with an ethylenically unsaturated mono- or dicarboxylic acid or the anhydride thereof, and then by derivatizing with a primary or secondary amine and/or alcohol, and also ofb) Casein.These flow improving agents have the advantage that the ability to flow is considerably improved in comparison, for example, with casein alone, and the improved ability to flow is preserved over a longer period of time.
