“…Synthetic bioceramics can be classified into several groups according to their silicate content (Figure ) (Müller, ; Bengisu, ) because silicate seems to play a vital role in bone tissue engineering (Oliveira, Malafaya, & Reis, ; Gaharwar et al., ; Xavier et al., ). Calcium sulphate, calcium phosphate (CaP) ceramics, bioactive glass and combinations thereof are the most common synthetic bone substitutes available at present (Yang, Lin, Zhang, & Gou, ).…”

Bovine xenograft materials, followed by synthetic biomaterials, which unfortunately still lack documented predictability and clinical performance, dominate the market for the cranio‐maxillofacial area. In Europe, new stringent regulations are expected to further limit the allograft market in the future. Aim Within this narrative review, we discuss possible future biomaterials for bone replacement. Scientific Rationale for Study Although the bone graft (BG) literature is overflooded, only a handful of new BG substitutes are clinically available. Laboratory studies tend to focus on advanced production methods and novel biomaterial features, which can be costly to produce. Practical Implications In this review, we ask why such a limited number of BGs are clinically available when compared to extensive laboratory studies. We also discuss what features are needed for an ideal BG. Results We have identified the key properties of current bone substitutes and have provided important information to guide clinical decision‐making and generate new perspectives on bone substitutes. Our results indicated that different mechanical and biological properties are needed despite each having a broad spectrum of variations. Conclusions We foresee bone replacement composite materials with higher levels of bioactivity, providing an appropriate balance between bioabsorption and volume maintenance for achieving ideal bone remodelling.

“…Borates are well known for their extended glass forming range and the fact that they form glasses with oxides of many different elements of the periodictables . Borate glasses are also known for their structural variations and wide variety of superstructural units, and consequently also for their wide range of physical properties and applications . Products include, but are not limited, to sealing glasses with low melting temperatures, ion conducting glasses, and materials for optical applications .…”

“…Products include, but are not limited, to sealing glasses with low melting temperatures, ion conducting glasses, and materials for optical applications . The latter include photoluminescent or nonlinear optical materials, due to the extremely good solubility for rare earth or transition metal ions in borate glass systems . Rare earth‐doped alkali borate glass was investigated as a promising optical fiber and NIR laser medium while showed that the addition of PbO prevented crystallization in borate glasses.…”

“…However, for neutron detection, a constituent ion of high neutron absorption such as B ion is necessary. One typical subset of borate glass systems encompasses borate glasses with high barium or lead levels which are characterized by high refractive indices and low T g . Many studies can be found in the literature regarding the structure of lead‐containing glasses, with special focus on the changing role of lead from network modifier at low PbO concentrations to network former at high PbO levels, even forming a PbO‐pseudophase .…”

Glasses of the ternary lead-barium borate series (70−x) B 2 O 3 -30 BaO-xPbO with x = 0.05 to 30 mol% were studied for their optical properties by photoluminescence (PL) and UV-Vis absorption spectroscopy. Variations in the s-p transition of Pb 2+ were followed as variations of the lead content and varying optical basicities of the glass. The UV cutoff of the undoped glass sample is observed at about 340 nm and increasing PbO addition results in a red shift of the optical absorption edge to 480 nm for the glass with x = 30 mol%. In lead barium borate glasses, the emission intensity increases up to 4 mol% PbO before decreasing at higher PbO levels. Additionally, the series was studied regarding structural variations by Raman and infrared spectroscopy. The fraction of tetrahedrally coordinated [BO 4/2 ] − and of trigonal borate units with nonbridging oxygen atoms (metaborate and pyroborate) increases with PbO addition. The molar volume of the prepared glasses is found to increase with increasing lead content. The glass basicity, as determined from the composition, correlates well with the position of the lead excitation band.

“…Many solid state devices in modern nonlinear optics, acoustic-electronics and optoelectronics are impossible without these advanced materials. The creation of new perfect borate crystals is also impossible without an essential development of crystal growth methods and further investigation of physical chemistry of multicomponent borate melts, glasses, solutions, and crystals [147,148].…”

Abstract:The structure and the maximal nonlinear optical (NLO) susceptibility χ (2) are tabulated for more 700 acentric binary oxides, 220 crystals of simple, binary and complex borates and for the same set of 110 carbonates, tartrates, formates, oxalates, acetates and fluoride-carbonates used in ultraviolet and deep ultraviolet optoelectronics. According to the chemical formula, the structural symbols of these crystals have been plotted on the plane of two minimal oxide bond lengths (OBL). It is shown that acentric crystals are positioned on such plane inside the vertical, horizontal and slope intersected ellipses of "acentricity". The oxide and borate crystals with moderate NLO susceptibility are found in the central parts of these ellipses intersection and, with low susceptibility, on top, at the bottom and border of the ellipses rosette. The nonpolar fluoride-carbonate crystals with high NLO susceptibility are found in the curve-side rhombic parts of the slope ellipse of "acentricity". The unmonotonous fuzzy dependence "χ (2) " on the OBL of these crystals is observed, and their clear-cut taxonomy on compounds with π-or σ-oxide bonds is also established. It is shown that the correlations of χ (2) with other acentric properties are nonlinear for the whole set of the oxide crystals having their clear maximum at a certain value of the piezoelectric or electro-optic coefficient. The correlation "hardness-thermoconductivity-fusibility" is plotted for oxide crystals, part of which is used at the creation of self-frequency-doubling solid state lasers.
