 ILL : ANNUAL REPORT 2001
Silicate melts have great relevance both in earth science and technology: physical properties of magma (molten silicate rock) dominate many geological processes and technological glasses are synthesised from the molten state.
A considerable effort has been made to investigate a wide range of silicate melts with the general aim of linking structural with physical properties and to develop an atomic level understanding of their structure and dynamics [1].
The concentration of sodium in these channels implies that the Si-O network is less disrupted in the rest of the system leading to a higher viscosity of the entire system and thus may equally explain the weak temperature dependence of the viscosity in sodium silicate melts at high temperatures.

 TAPPI Website - Addition of Sodium Silicate and Chelant to the FAS Stage to Bleach Recycled Fibers, 1999 Pulping ...
In this paper we report that when sodium silicate instead of sodium hydroxide is used for pH control during the FAS treatment, a better bleaching result can be obtained.
Furthermore, when both chelant and sodium silicate are added to the FAS stage, followed with a peroxide stage (a FP sequence), the final brightness of the resulting pulp is higher than the control FP sequence.
The improved bleaching in the peroxide stage is a result of enhanced removal of transition metal ions due to the combined actions of reduction and chelation in the FAS stage, which precedes the peroxide stage.
