“…Some of these phases are very detrimental due to their low thermal expansion. Therefore, based on earlier studies [13][14][15][16] on glass and glass ceramics a glass composition SiO 2 -B 2 O 3 -BaO-A 2 O 3 (A = Y, La, Al, Cr) was selected for the present study. Effect of field strength of intermediate cations on the crystallization kinetics, formation of various crystalline phases and change in thermal properties of the glasses are studied.…”

“…The first rise of temperature rate was 10 °C min -1 and it was hold at 900 °C for 1 h to achieve the decarbonation of all products. The second rise of temperature rate was 20 °C min -1 and it was hold to 1,350 °C for 3 h. The thermal elaboration process was described in Fig T g and T onset c introduced by Dietzel [22][23][24]:…”

To cite this version:Eric Wers, Hassane Oudadesse. Thermal behaviour and excess entropy of bioactive glasses and Zn-doped glasses.. Journal of Thermal Analysis and Calorimetry, Springer Verlag, 2013, pp.1-8. of pure bioactive glass elaborated with different amounts of CaO, Na 2 O in pure glass and with different amounts of introduced Zn in glass (ranging from 0.1 to 10 in wt%), were studied. The excess entropy was calculated for different compounds. Glasses were prepared by the melting process. The thermal behaviour of obtained bioactive glasses was determined using differential thermal analysis. Therefore, the glass transition (T g ), the crystallization (T c ) and the melting temperatures (T f ) were revealed. Moreover, according to Dietzel formula, the thermal stability (TS) of the studied bioactive glasses has been calculated. The first results concerning the impact of different oxides, revealed a decrease of the TS, T g , T c and T f when the SiO 2 /CaO increases and revealed an increase of these thermal characteristics when the SiO 2 /Na 2 O and CaO/Na 2 O ratios increase. Introducing Zn into the bioactive glasses induces a decrease of T f and an increase of TS. Contrary to crystals, prepared glasses have entropy different to zero at T = 0 K and vary versus T f . The excess entropy of pure glasses and Zn-doped glasses were calculated. The significant variations were registered.
