Influence of composition and preparation conditions on some physical properties of TeO2–Sb2O3–PbCl2 Glasses

Anomalous properties of chloroborosilicate glasses in the K2O–BaO–Al2O3–B2O3–SiO2–BaCl2 system

“…For this system the degradation of glass in the presence of moisture is very small as compared to the halide glasses. 37 Oxychloride glasses in the Sb 2 O 3 -CdCl 2 -SrCl 2 system is fairly stable having average glass transition around 300 • C. 38 In recent times it was observed that the lead-antimony-tellurium oxychloride system with composition 70TeO 2 -10Sb 2 O 3 -20PbCl 2 forms stable glasses in a broad range of compositions as reported by Bošák et al 39 Ternary glasses have been synthesized and studied in the Sb 2 O 3 -PbCl 2 -MoO 3 system by Goumeidane et al 40 The glass-forming regions in the PbCl 2 -PbBr 2 -P 2 O 5 system were explored by Zhou et al 41 Oxychloride glasses based on the TeO 2 -ZnO-ZnC1 2 system provides a wide and stable glass formation range in which a T c -T g gap beyond 140 • C. 42 Bulk oxychloride glasses have been prepared in the TeO 2 -ZnO-ZnCl 2 and TeO 2 -PbO-PbCl 2 systems, they yield stable glass of good optical quality. 43 Barium chloride-oxide tellurite glasses in the system BaCl 2 -BaO-TeO 2 are studied by Sokolov et al 44 where continuous network of barium chloride-oxide tellurite glass has been proved to be formed.…”

Synthesis of transparent chloroborosilicate nanoglass-ceramics: Crystallization and growth mechanism of BaCl2 nanocrystals

“…Glass formation in the Sb 2 O 3 -CdCl 2 -SrCl 2 ternary system was reported by Iezid et al They exhibited low-phonon energy [19]. Recently, the properties of 70TeO 2 -10Sb 2 O 3 -20PbCl 2 composition are reported [20]. Ternary glasses have been synthesized and studied in the Sb 2 O 3 -PbCl 2 -MoO 3 system [21].…”

Structural, electrical and dielectric characterization of TeO 2 –WO 3 –Y 2 O 3 –Er 2 O 3 –Yb 2 O 3 glasses

“…As in the dc case, the temperature dependence of the σ ac plots was linearized in the range of high temperatures using the Arrhenius equation (1). We must mention that in this case the data dispersion is bigger than the one observed for the dc conductivity.…”

“…TeO 2 based glasses are of high scientific and technological interest, especially for optical communication systems and optoelectronic applications, due to their advantageous properties such as good infrared transmissivity, relatively low phonon energy, high refractive index, high density, good thermal and chemical stability, high devitrification resistance and high dielectric constant [1,2]. Although frequently tellurium dioxide is labelled as a glass former, it is sometimes referred as a conditional glass former, since it does not form a glass under usual quenching conditions due to a high tendency for crystallization [3].…”
