Abstract

Sintered composites of silica-containing Na2WO4 as a phase transformation agent and sodium borosilicate glass were prepared, and silica polymorphs in silica/glass sintered composites were identified and quantitatively analyzed by means of XRD. The amount of tridymite increased with the addition of Na2WO4. It was found that the thermal expansion is controllable by the amount of silica polymorphs, particularly tbat of tridymite, in silica/glass composites. Addition of Na2WO4 to the composites increased the dielectric constant, which may be attributed to the increase in the amounts of sodium and tungsten ions which have high polarizabilty.
