  • Method of converting limestone into tri-calcium phosphate and tetra-calcium phosphate powder simultaneously
    Patent number: 9718687
    Abstract: The present invention relates to a method of converting limestone into tri-calcium phosphate (TCP) and tetra-calcium phosphate (TTCP) powder simultaneously. In particular, the method provides for a method of converting limestone into TCP and TTCP powder simultaneously having specific particle size and with specific crystallographic structure.
    Type: Grant
    Filed: September 29, 2011
    Date of Patent: August 1, 2017
    Assignee: SIRIM Berhad
    Inventors: Fazilah Binti Fazan, Sudirman Bin Sahid, Wan Ruzaini Bin Wan Sulaiman, Nor Shahida Binti Kader Bashah
  • Composition containing injectable self-hardened apatite cement
    Patent number: 9427492
    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.
