The common AZS bricks are zirconium corundum bricks, which are most often used in the glass kiln industry. There are three common models: AZS33#, AZS36# and AZS41#. The following is a detailed description of the distinction.

1.Fused zirconium corundum brick AZS33#:

The dense microstructure of zirconium corundum bricks makes the bricks resistant to glass liquid erosion and not easy to produce stones or other defects in the glass kiln. It is a widely used product in glass kilns, mainly suitable for the upper structure of the melting pool, the pool wall bricks and paving bricks of the working pool, the material channel, etc..

AZS33# is a product with a relatively large usage in the fused AZS series of products, and it has excellent performance in preventing contamination of glass liquid. It is widely used in the pool wall, pool bottom, upper structure and supply channel of glass kilns.

2.Fused zirconium corundum brick AZS36#:

In addition to the same eutectic brick resistance as AZS33# fused zirconium corundum brick, 36# AZS brick has more chain-like zirconium oxide crystals and lower glass phase content, so the erosion resistance of 36# fused zirconium corundum is further enhanced, so it is suitable for areas with fast glass flow rate or high temperature.

AZS36# has high resistance to glass erosion and low pollution characteristics, and is usually used in key parts such as the pool wall near the hot spot of the glass melting furnace melting pool.

3.Fused zirconium corundum brick AZS41#:

In addition to the eutectic of silicon oxide and aluminum oxide, AZS41# fused zirconium corundum brick also contains more uniformly distributed zirconium oxide crystals. Its erosion resistance is the best in the zirconium corundum brick system. Donc, it is selected for the key parts of the glass furnace to balance the life of these parts with other parts.

AZS41# has extremely high resistance to glass erosion and extremely high glass phase seepage temperature, and has extremely low pollution to glass. It is widely used in key locations such as glass furnace wall at hot spots, corners of feeding ports, liquid flow holes, kiln sills, bubbles at the bottom of the furnace and all-electric melting furnaces.
