“…The broadband at 1460 cm À 1 is attributed to the asymmetric stretching of CO 3 2À group. [36,47] A similar kind of FT-IR spectra was observed for wollastonite/forsterite composites which are illustrated in figure 11b. The vibrational modes at 511 cm À 1 and 611 cm À 1 indicate the presence of OÀ P-O bending vibrations.…”

“…The absorbance peak at 999 cm −1 reveals the existence of O−P‐O stretching vibrations. The presence of CO 3 2− functional group is confirmed by the asymmetrical stretching vibrations observed at 1471 cm −1 . In addition to the formation of carbonated apatite with the presence of CO 3 2− and PO 4 3− , peaks related to Si−O and O−Si‐O groups are appeared in the spectrum due to the mixing of composite material when subjected to the experiment.…”

Bioceramics used in hard tissue engineering applications should primarily meet the criteria of mechanical strength and apatite mineralisation of natural bone. In such a scenario, designing of bioceramic composites is inevitable as calcium silicates possess good apatite deposition ability and magnesium silicates show excellent mechanical stability. The present study investigates the influence of calcium (Ca) and magnesium (Mg) ions of the bioceramics on bioactivity and mechanical strength. Binary silicates such as wollastonite (CaSiO3), enstatite (MgSiO3) and forsterite (Mg2SiO4) were prepared by sol‐gel combustion technique. Functional group identification and phase formation of the silicate materials were analysed by FT‐IR and X‐ray diffraction studies respectively. Furthermore, apatite mineralisation ability and mechanical strength of wollastonite were evaluated. Influence of wollastonite on the bioactivity of both enstatite and forsterite was also investigated. The obtained results conferred that the wollastonite possesses good apatite formation ability, moderate resorbability and low mechanical strength. The composites of wollastonite show improvement in the enstatite with respect to bioactivity and in forsterite with respect to superior mechanical properties.

“…Modification and improvement of its properties for different applications were extensively studied. Example are the use of diopside in medical applications, cell engineering, and biological adaptations by doping diopside with the elements strontium, manganese and fluoride [12][13][14][15]. For the same reason, the inoculation of diopside with monovalent elements [16] was also studied to improve the viability and degradability.…”

“…This type of crystal provides a favorable situation for ionic conduction due to the presence of copper in the fourfold sites, and, therefore, its presence in the crystalline state increases the superconductivity [25]. Among the many routes of synthesis of Cu-diopside doped materials as sol-gel, co-precipitation and melting, [12,26], the last procedure was chosen in our study for its simplicity and ease to prepare Cu-diopside doped materials. The present work reports a study of single-step crystallization processes of Cu-containing diopside Cux(CaMg)2-xSi2O6 glasses by aid of nucleating catalysts like TiO2, Cr2O3, or CaF2.…”

The incorporation of copper into pyroxene structure was investigated through the melt quenching technique and one-step crystallization procedure. Two series of glasses have been studied, one set with Ca=Mg and another set with Ca>Mg in diopside formula Cux(Ca Mg)2-xSi2O6. The glasses were nucleated by TiO2, Cr2O3, or CaF2 additions as nucleating agents to variably control the phases produced. X-ray diffraction (XRD), scanning electron microscopy, and energy-dispersive X-ray spectroscopy (EDX) were used to characterize the obtained samples. The heat treatment studied at 700, 800, 900 and 1000 °C for 2 h produced green and dark green glasses based on Cu-containing diopside. Various crystalline wollastonite, cuprite, tenorite, cristobalite, quartz, and fluorite phases were developed with different ratios combined with diopside formation depending on the heat treatment and nucleating agents used. As the heat treatment increased in temperature, the crystallized fraction increased with the development of nano-aggregates and the observed reticulated textures confirmed a radical change in the euhedral crystals. This emphasizes that the Cu-containing diopside can be created by a facile one step process. These compositions may find some applications in biological and optical fields.
