IMPROVED REFRACTORY COMPOSITIONS SUITABLE FOR USE IN FLUID BED CHLORINATORS

This invention provides new refractory binder compositions comprising silica and titania which can be used to make ceramic bodies, particularly bricks. The refractory binder compositions comprise about 70 to about 92 wt.% silica (SiO2) and about 8 to about 30 % titania (TiO2). The refractory binder...

Beschreibung
Zusammenfassung:	This invention provides new refractory binder compositions comprising silica and titania which can be used to make ceramic bodies, particularly bricks. The refractory binder compositions comprise about 70 to about 92 wt.% silica (SiO2) and about 8 to about 30 % titania (TiO2). The refractory binder compositions may further comprise alumina and a metal oxide selected from the group consisting of calcium oxide, strontium oxide, and sodium oxide, and mixtures thereof. The refractory ceramic bodies can be used in hot corrosive/erosive environments such as in fluid bed chlorinators in the manufacture of titanium dioxide.
