Fused cast AZS Block is also known as fused zirconia corundum block,named as electrocast AZS refractory blocks and the abbreviated is AZS, according to the three chemical components of the Al2O3-ZrO2-SiO2 and Al2O3 takes A, ZrO2 takes Z, SiO2 takes S.

Ceramic tube, usually be called alumina tube, it can be widely used in the different kiln.It can be work between 1100℃ to 1710 ℃. According to different temperature, it is divided into 99.7% (corundum tube), 99 % (corundum tube), 95% (corundum tube), 85 % (high aluminum tube), 75 % (mullite mute), normal standard (40% aluminum tube).
