Lithium Carbonate/Sodium Sulfate Eutectic—An Additive for Improving Glass Production
Source abstract
Abstract
A phase diagram for the system lithium carbonate/sodium sulfate was developed by DTA measurements in a CO 2 atmosphere. The lithium carbonateisodium sulfate eutectic composition from that system improved glassmelting, speeded fining, and reduced the viscosity of a standard fiber glass when used as an additive. Improved melting rates were postulated to result from reaction of lithia with glass‐forming components at a relatively low temperature. Lithia is formed by decomposition of Li 2 CO 3 or Li 2 CO 3 /Na 2 SO 4 eutectic in air at or near their melting points.
