The calculation of glass properties (glass modeling) is used to predict glass properties of interest or glass behavior under certain conditions (e.g., during production) without experimental investigation, based on past data and experience, with the intention to save time, material, financial, and environmental resources, or to gain scientific insight.
The technology for perlite/sodium silicate composite manufacture is based largely on this foundry industry experience. A variety of solid-state NMR techniques were applied in order to assign resonances in the 29Si and 23Na NMR spectra of a new crystalline silicate to crystallographically distinct silicon and sodium sites, respectively.

essing operations resulted in overall recovery of 99.8% of the U from Al-U type fuels (12 varieties) available for processing. Dissolution and first cycle extraction were conducted nt an average rate of 24 kg of U per day for MTR- ETR fuel and at lower rates for other fuels; overall plant and individual cycle decortamination was equivalent to that of earlier Al processing runs.
We demonstrate that silicate bonding an optical flat to the output facet of an active fiber device can increase the reliability of high-peak power systems and subsantially reduce the effective feedback at the termination of a double-clad fiber. We determine the bonding parameters and conditions that maximize the optical damage threshold of the bond and minimize the Fresnel reflection from the ...

It consists of sodium silicate embedded in silicone. Since sodium silicate is polar and silicone is not, no mixing of the two substances occurs. The Stokes center wavelength was tuned to detect resonances in the region 2800–3000 cm –1. Silicone presents peaks at 2906 and 2965 cm –1 associated with its CH-stretching modes, while sodium ...
