Calcium-magnesium-silicate glass fiber is a kind of candidate materials for aluminosilicate ceramic fiber in high temperature resistant field.
Experimental The major starting materials are wollastonite, silica and Al2O3 (analytical reagent).
After thoroughly mixed, the weighed batch materials were melted in a graphite crucible at 1600-1800˚C for 30-50min.
The temperature of Tc and the shape of exothermic peak shape indicate the crystallization behavior of glassy materials, and the range between Tg and Tc shows the ability to be formed into glassy materials for the studied compositions.
