[GENERAL INFORMATION]

Fused cast AZS (alumina, zirconia and silica) refractories are good refractory materials, especially for current
glass furnaces, and characterized with excellent density, high refractoriness and resistance against corrosion
of molten glass. The applications are popularly found in many key positions of various glass furnaces. Fused
cast AZS firebricks are mainly categorized into 33#, 36# and 41# according to different zirconia's contents
from 33% to 41%.

[ADVANTAGES]

* Good resistance to corrosion of molten glass;

* Low blistering rate;

* Little tendency to release zirconia crystal into molten glass;

[APPLICATION]

* Sidewalls;

* Breast walls;

* Ports;

* Pavers;
