24 Apr 2014-Journal of Physics C: Solid State Physics (American Institute of PhysicsAIP)-Vol. 1591, Iss: 1, pp 745-746
TL;DR: In this paper, the structural properties of magnesium and zinc doped 45S5 samples have been studied by XRD, FTIR and SEM techniques and the results may be useful to improve the antibacterial as well as osteoblast properties of the currently available bioactive materials.
Abstract: Magnesium and zinc doped 45S5 samples were prepared in the laboratory by sol gel technique., Structural properties of the samples have been studied by XRD, FTIR and SEM techniques. Both FTIR and XRD data indicate the primary bioactive behavior of the samples. Presented results may be useful to improve the antibacterial as well as osteoblast properties of the currently available bioactive materials.

TL;DR: In this article , a mixture of mixed-anionic aqueous solutions is used to obtain active powders for bioceramics production in the CaO-SiO2-P2O5-Na2O system.
Abstract: Synthesis from mixed-anionic aqueous solutions is a novel approach to obtain active powders for bioceramics production in the CaO-SiO2-P2O5-Na2O system. In this work, powders were prepared using precipitation from aqueous solutions of the following precursors: Ca(NO3)2 and Na2HPO4 (CaP); Ca(NO3)2 and Na2SiO3 (CaSi); and Ca(NO3)2, Na2HPO4 and Na2SiO3 (CaPSi). Phase composition of the CaP powder included brushite CaHPO4‧2H2O and the CaSi powder included calcium silicate hydrate. Phase composition of the CaPSi powder consisted of the amorphous phase (presumably containing hydrated quasi-amorphous calcium phosphate and calcium silicate phase). All synthesized powders contained NaNO3 as a by-product. The total weight loss after heating up to 1000 °C for the CaP sample—28.3%, for the CaSi sample—38.8% and for the CaPSi sample was 29%. Phase composition of the ceramic samples after the heat treatment at 1000 °C based on the CaP powder contained β-NaCaPO4 and β-Ca2P2O7, the ceramic samples based on the CaSi powder contained α-CaSiO3 and Na2Ca2Si2O7, while the ceramics obtained from the CaPSi powder contained sodium rhenanite β-NaCaPO4, wollastonite α-CaSiO3 and Na3Ca6(PO4)5. The densest ceramic sample was obtained in CaO-SiO2-P2O5-Na2O system at 900 °C from the CaP powder (ρ = 2.53 g/cm3), while the other samples had densities of 0.93 g/cm3 (CaSi) and 1.22 (CaPSi) at the same temperature. The ceramics prepared in this system contain biocompatible and bioresorbable phases, and can be recommended for use in medicine for bone-defect treatment.
