Elastic and non-linear acoustic properties and thermal expansion of cerium metaphosphate glasses

Structural, mechanical and optical investigations in the TeO2-rich part of the TeO2–GeO2–ZnO ternary glass system

“…Moreover, this fact is well confirmed by the evolution of the fractal bond connectivity d. This parameter is calculated using equation given in section 2. Fractal Bond connectivity is a very useful parameter which could provide information about the effective dimensionality of the glass network [44,45]. Bogue and Sladek [46] suggested that the value of d is 3 for 3D networks, 2 for 2D layer structures and 1 for 1D.…”

Correlation between acoustical and compositional parameters of borate and tellurite glasses

“…Fractal bond connectivity, d ¼ 4 SK À1 , where S is shear modulus, is another useful parameter relating the elastic properties of glasses to their structures [24,25], since its value provides information about the effective dimensionality of the glass network. Bogue and Sladek [31] suggested that the value of d is 3 for 3D networks of tetrahedral coordination polyhedral, 2 for 2D layer structures and 1 for 1D chains.…”

Thermal properties of 60P2O5–(40−x)Al2O3–xNa2O glasses

“…The glasses containing Ca can be biocompatible and can be used as bone or dental implants [2][3][4][5][6][7]. Addition of rare earths makes them attractive materials for laser and optoelectronic devices [8][9][10][11][12][13][14]. Phosphate glasses can be also used as fertilizers of slow and controlled dissolution [15][16][17].…”
