Structural analysis and thermal behavior of diopside–fluorapatite–wollastonite-based glasses and glass–ceramics

Design, selection and characterization of novel glasses and glass-ceramics for use in prosthetic applications

“…Therefore, higher S c are related to higher final densities, which indicates a better sintering behaviour that involves a higher densification of the final sample. Table 3 gives a comparison among the thermal parameters calculated for S57A7 and S50B2 in the present work and those available in the literature for other biomedical SiO 2 -based glasses [22,32,33]. The parameters δ and K H of both S57A7 and S50B2 are superior to those of all the other glasses reported.…”

Synthesis and in vitro bioactivity assessment of injectable bioglass−organic pastes for bone tissue repair

“…In the last few years, an effort has been made to design and to process bioactive glasses in the CaO-MgO-SiO 2 system aiming at their applications in human biomedicine [14][15][16][17][18]. The glass compositions were selected in the primary crystallization field of pseudo-wollasotine phase in the ternary CaOMgO-SiO 2 diagram doped with P 2 O 5 , Na 2 O, CaF 2 and B 2 O 3 in order to obtain glasses with their silicate glass network being dominated by Q 2 (Si) species [19][20][21]. The investigated glass compositions exhibited high rates of bioactivity in vitro, i.e., excellent biomineralization upon immersion in simulated body fluid, stimulation of osteoblast proliferation in cell culture medium, and no evidence of any toxicity or other detrimental effects in the functionality of cells.…”

Alkali-free bioactive diopside–tricalcium phosphate glass-ceramics for scaffold fabrication: Sintering and crystallization behaviours

“…The homogeneity of particle packing the green samples, and various physical processes (entrapped insoluble gases, crystallization) occurring at the very end of the sintering process might also affect the densification kinetics. DTA and HSM are useful tools for investigating the effects of glass composition on sintering and devitrification phenomena as shown in some previous works from our group [17][18][19][20][21].…”

“…Diopside (Di) is an important member of the class of pyroxenes. The good mechanical properties and bioactivity of diopside based glasses and glassceramics have attracted much interest for bone tissue engineering applications in the recent years [12][13][14][15][16][17][18][19][20][21].…”
