The Use of Borates in Glass Melting
2008Commercial use of borates in glasses is surveyed. Structural and chemical differences between silica and borates are presented. Technical benefits of boron are reviewed for several major industrial borosilicate glasses and the major borate raw materials are discussed.

Microseparation in Lead Borate Glasses
Journal of the American Ceramic Society, 1966The microstructure of a series of lead borate glasses was studied by electron microscopy and small‐angle X‐ray scattering techniques. Although the glasses were optically homogeneous, microheterogeneities of the order of 2000 to 3000 A were detected in glasses with compositions near the region of two‐liquid stability.

Phosphate and Borate Bioactive Glasses
2022Inorganic glasses are successfully used in the biomedical field, in particular degradable glasses have found applications in tissue engineering, bone regeneration and tooth remineralisation. Silicate glasses are the most commonly used ones but phosphate and borate glasses are attracting more and more interest owing to their special properties ...

6Li NMR in lithium borate glasses
Solid State Nuclear Magnetic Resonance, 2008In anticipation of using fluctuations in the nuclear dipolar and quadrupolar interaction as a probe of lithium ion motion in lithium borate glasses, the static values of these interactions were measured using a variety of echo techniques. The static quadrupolar echo spectrum of (7)Li and a calculation of the dipolar interaction in crystalline Li(2)B(4 ...

Structural models for borate glasses
Journal of Non-Crystalline Solids, 1985Abstract Neither the Levedev crystalline model nor the Warren and Zachariasen random network model is appropriate for borate glasses. But Jan Krogh-Moe, perhaps building on the ideas of G. Hagg which were disputed by Zachariasen, suggested that borate glasses should contain the larger structural groupings (boroxol, diborate, metaborate, etc.) that ...

Acoustic properties of borate glasses
2004The attenuation and velocity of ultrasonic waves of frequencies in the range from 10MHz to 50MHz have been measured in (M2O)0.14(B2O3)0.86 borate glasses (M = Li, Cs or Ag) as a function of temperature between 15K and 300K. Broad relaxation peaks characterize the acoustic attenuation at temperatures below 100K and are paralleled by corresponding ...

Color centers in borate glasses
Vetro e Silicati, 1966The color centers of the alkali borate glasses are discussed in terms of structural units. The radiation-induced color centers in these glasses are studied by means of optical absorption and E.S.R. The absorption bands of the 2 types of spectra are correlated to the various types of structural units present in these glasses and a no.
