“…This heating protocol was employed to mitigate the influence of metastable crystalline phases on the analysis. The room temperature Raman spectra show two principal bands: 620 cm −1 as the P-O flexion band and within the 800-1100 cm −1 range as the Q region [31]. However, the high-temperature Raman spectra at 100 • C, 700 • C, and 1300 • C showed that the P-O flexion band disappeared at 620 cm −1 after heating.…”

This study demonstrated for the first time an in situ high-temperature fiber-optic Raman probe to study the structure of glass and slag samples at temperatures up to 1400 • C. A customized external telescope was integrated into a portable fiber-optic Raman probe to extend the optical working distance to allow the probe to work in a hightemperature environment. Three samples were evaluated to demonstrate the functionality of the high-temperature fiber-optic Raman probe. Room temperature and high-temperature Raman spectra were successfully collected and analyzed. In addition, a deconvolution algorithm was used to identify peaks in the spectrum that could then be related to the molecular structure of components in each sample. This flexible and reliable hightemperature Raman measurement method has great potential for various applications, such as materials development, composition, and structure monitoring during high-temperature processing, chemical identification, and process monitoring in industrial production.

“…Moreover, Sr ions give anticorrosive properties to the bioactive glass when it is used to coat stainless steel scaffolds [135,211]. Strontium ions present in the 45S5 bioactive glass increase the hardness of the composite material without affecting the elastic modulus of the bioactive glass [212].…”

“…The presence of magnesium ions increases the degree of dissolution of the bioactive glass, but, at the same time, decreases the crystallization rate of hydroxyapatite on the surface [203,218]. Magnesium particles dispersed in bioactive glass improve its mechanical properties [212,219,220].…”

Diseases or complications that are caused by bone tissue damage affect millions of patients every year. Orthopedic and dental implants have become important treatment options for replacing and repairing missing or damaged parts of bones and teeth. In order to use a material in the manufacture of implants, the material must meet several requirements, such as mechanical stability, elasticity, biocompatibility, hydrophilicity, corrosion resistance, and non-toxicity. In the 1970s, a biocompatible glassy material called bioactive glass was discovered. At a later time, several glass materials with similar properties were developed. This material has a big potential to be used in formulating medical devices, but its fragility is an important disadvantage. The use of bioactive glasses in the form of coatings on metal substrates allows the combination of the mechanical hardness of the metal and the biocompatibility of the bioactive glass. In this review, an extensive study of the literature was conducted regarding the preparation methods of bioactive glass and the different techniques of coating on various substrates, such as stainless steel, titanium, and their alloys. Furthermore, the main doping agents that can be used to impart special properties to the bioactive glass coatings are described.
