Abstract

Glass-forming region in the system ZrO2-WO3-Al203 was determined by melting and quenching method with Pt crucible, and thermal expansion of glasses was measured. The glass-forming region in ZrO2-WO3-Al2O3 system was found to be the vicinity of the composition of 20mol%ZrO20mol%WO30mol%Al2O3. In ZrW2O8-Al2(WO4)3 glasses, thermal expansion coefficient decreased slightly with increasing Al2(WO4)3 content.
