“…In fact, such technique is very useful in order to confirm the precipitation of apatite in vitro, as the Raman peaks related to the P-O vibration modes are particularly intense. In the spectrum of Figure 3c, acquired on the phosphorus and calcium rich precipitates after 7 and 14 days in SBF, it is possible to identify the main peaks ascribable to apatite, which arise from phosphate ions [19,20]. In more detail, the spectrum is dominated by a particularly sharp peak at ~960 cm −1 , which, in the literature, is referred to as the ν 1 symmetric stretching vibration of phosphate anions; moreover, it is possible to observe two further broad peaks which progressively emerge from the background, i.e., at ~430 cm −1 and 590 cm −1 (see the arrows in Figure 3c), where the literature reports the presence, for apatite, of peaks ascribable to the ν 2 and ν 4 bending modes of the (PO 4 ) 3− group [19][20][21].…”

The recent research on bioactive glasses (BGs) has mainly moved on two fronts: (1) introducing ions of therapeutic interest in their composition and (2) the development of scaffolds, fibers, coatings and sintered products starting from BGs in powder form. In this case, the main obstacle to overcome is that BGs rapidly crystallize during heat treatments, thus transforming into glass-ceramics with low reactivity, slow ion release and, eventually, poor mechanical properties. Here an innovative bioactive glass (BGMS_LS), capable of responding to the main limitations of commercial BGs, is presented. The new material contains strontium and magnesium, whose therapeutic relevance is well known, and can be sintered at extraordinarily low temperatures without crystallizing, thus keeping all of its biological potential intact.

“…Aside from the many review papers [ 238 , 239 , 240 , 241 ] that give a useful and exhaustive insight into the achievements so far in present area, there is intensive ongoing research on the further development of both the composition of the bioactive glass composite coatings and optimization of their preparation method, which is the key factor of the goodness of the adherence. One of the perfect examples is the up-to-date work of Canas et al [ 242 ], wherein an innovative and appropriately optimized bioactive glass material was applied as a coating on stainless steel substrates by plasma spraying technique. The powder for the coatings was prepared by melt-quenching.…”

Bioactive glasses (BGs) are especially useful materials in soft and bone tissue engineering and even in dentistry. They can be the solution to many medical problems, and they have a huge role in the healing processes of bone fractures. Interestingly, they can also promote skin regeneration and wound healing. Bioactive glasses are able to attach to the bone tissues and form an apatite layer which further initiates the biomineralization process. The formed intermediate apatite layer makes a connection between the hard tissue and the bioactive glass material which results in faster healing without any complications or side effects. This review paper summarizes the most recent advancement in the preparation of diverse types of BGs, such as silicate-, borate- and phosphate-based bioactive glasses. We discuss their physical, chemical, and mechanical properties detailing how they affect their biological performances. In order to get a deeper insight into the state-of-the-art in this area, we also consider their medical applications, such as bone regeneration, wound care, and dental/bone implant coatings.

“…From this glass, several researchers have developed variants over time by slightly modifying the composition of this glass (substitution and/or elimination of oxides) depending on the application or method of synthesis. Some examples are the bioactive glass 58S [92], without sodium, as it is typically synthesised by the sol-gel method, the Bio-K [93], which includes potassium instead of sodium in order to reduce the crystallisation tendency of the glass, or the BGMS10 [94], which includes magnesium and strontium to highly increase the crystallisation temperature.…”

“…Like HAp, these glasses are deposited by different techniques, i.e., APS, SPS, HVSFS and SPPS [94,[97][98][99][100][101][102]. The use of liquid materials results in more porous and rougher microstructures, which increase the bioactivity of the coatings.…”

Advanced ceramic coatings have been largely used in several industrial fields such as aerospace, automotive, power generation, medical or petrochemical, in order to protect or functionalise the surface of different materials. In modern industries, thermal spray processes are the most used ones to manufacture advanced ceramic coatings due to their cost advantages, flexibility and efficiency in processing ceramic materials, especially those with high melting temperature. This chapter provides a brief overview of the progress and current state of different thermal sprayed ceramics and summarises the future trend in this field. Therefore, various advanced ceramics, such as yttria-stabilised zirconia, alumina, hydroxyapatite and bioactive glasses, have been selected for analysis and discussion.
