Research ArticleOpen accessIn the keywordsNew Low-Temperature Technology of Producing Calcium Feed Phosphate with MicroelementsJózef HoffmannThe possibility of producing feed calcium phosphates in a way ensuring a low physical water content in the product was investigated in laboratory conditions. For this purpose the process use of a phosphoric acid solution with a higher (than in conventional methods) P2O5 content (53-63% by wt. P2O5) with CaO (molar fraction of 0.5-0.8) and CaCO3 in the phosphoric acid … …American Journal of Agricultural and Biological Sciences, Vol. 2, Issue 4 · 31 Dec 2007 · 7,739 accessesView PDF Cite

Research ArticleOpen accessIn the abstractInfluence of Degrading Calcium Phosphate on the Remodelling and Mineralisation of Avascular Osseous Tissue in a Rat Calvaria ModelTulio Fernandez, Carlos H. Valencia, Yuann Li et al.Artificial bone graftingis the subject of intensive investigation for craniofacial reconstruction. Among the syntheticcandi date materials, those incorporating Calcium Phosphates (CaP) have gained popularity, due to their osteoinductive properties. Despite many quantitative studies on the degradation rates of CaP biomaterials in vitro, there is lack of quantitative studies in relation to bone remodelling kinetics in vivo. In this investigation, we … …American Journal of Biochemistry and Biotechnology, Vol. 11, Issue 1 · 24 Dec 2014 · 7,208 accessesView PDF Cite

Research ArticleOpen accessIn the abstractNanocrystalline Powders of Alkaline-Earth Phosphates as Precursors for BioceramicsParhi Purnendu, A. Ramanan, Alok R. RayBone is a nanocomposite made of calcium phosphates and collagen. Collagen has a typical fibrous structure, with diameter ranging from 100 nm to 2 μm. It is suggested that calcium hydroxyapatite, Ca10(PO4)6(OH)2 in the size range 5-50 nm embedded in the collagen framework provides mechanical strength to bone. Among calcium phosphates, apatites are found to be the most suitable for … …American Journal of Biochemistry and Biotechnology, Vol. 2, Issue 2 · 30 Jun 2006 · 6,543 accessesView PDF Cite

Research ArticleOpen accessIn the abstractNanoceramic Matrices: Biomedical ApplicationsWilli Paul, Chandra P. SharmaNatural bone consisted of calcium phosphate with nanometer-sized needle-like crystals of approximately 5-20 nm width by 60 nm length. Synthetic calcium phosphates and Bioglass are biocompatible and bioactive as they bond to bone and enhance bone tissue formation. This property is attributed to their similarity with the mineral phase of natural bone except its constituent particle size. Calcium phosphate ceramics … …American Journal of Biochemistry and Biotechnology, Vol. 2, Issue 2 · 30 Jun 2006 · 7,361 accessesView PDF Cite
