Results obtained by scanning electron microscopy (SEM) and x-ray diffraction (XRD) showed a composite with residual CaSiO3 and BaTiO3 powders as well as newly formed silica (SiO2), brushite...

Jan 19, 2022 · The XRD patterns of brushite, as well as the patterns of standard brushite, are shown in Figure 4. The mineralogy of the powder confirms that this precipitate produced after mixing NaH 2 PO 4 ·2H 2 O and Ca(NO 3 ) 2 ·4H 2 O solutions with a Ca:P molar ratio 1:1 ( Figure 1 ) is pure brushite, while its crystals grow after nucleation in ...

The XRD patterns of brushite, as well as the patterns of standard brushite, are shown in Figure 4 . The mineralogy of the powder confirms that this precipitate

In-situ X-ray diffraction (XRD) and in-situ ¹H nuclear magnetic resonance (¹H NMR) measurements proved the precipitation of brushite, as main phase, and monetite, indicating that Li⁺ favored ...

Jan 19, 2022 · In this chapter, besides its biomedical applications, the synthesis and properties of brushite were investigated. Brushite consists of two types of crystals, platy and needle-like, and their...

Abstract: Dicalcium phosphate dihydrate (DCPD) nanoparticles, also known as brushite, are considered an important bioceramic compound. In this study, brushite was prepared from Moroccan phosphogypsum (PG) using a new sol-gel method.

The substitution of Ca with Zn in brushite was studied by examining a range of Ca x Zn 1−x HPO 4 ·nH 2 O biomaterials, which underwent XRD, SEM, XPS, ICP, and TG analyses. The findings indicate that when the Zn/Ca molar ratio was below 0.25 in the starting solution, Ca was partly substituted by Zn.

Feb 17, 2021 · X-ray diffraction (XRD) scans were carried out with a PANalytical X’Pert PRO diffractometer in the Bragg–Brentano geometry. It was equipped with a Cu K source (λ = 1.5418 Å, 40 mA, 40 kV), and data were collected with a fast X’Celerator detector.

Jan 1, 2022 · Fig. 1 shows the XRD pattern of the synthesized powders and the standard for pure brushite (JCPDS 72-0713). These two patterns are very similar; therefore, it can be argued that the synthesized calcium phosphate is brushite having a monoclinic structure.

Jun 1, 2020 · The XRD pattern shows an exacerbated (020) line indicating significant preferred orientations of stacked constitutive crystallites, as is common with brushite crystals. In a subsequent step, crystal structure refinement has been performed.
