Introduction of α-β Alumina TY-M:

TY-M has no contamination of glass melt , dense structure , excellent corrosion resistance of glass melt below 1350℃。 It is the ideal refractory material for channel, feeder channel, spouts and working ends of glass furnace.

Al2O3 Chemical Composition: 94 %

SiO2 Chemical Composition: 1 %

NaO2 Chemical Composition: 4 %

α-Al2O3 Crystallographic Analysis: 44 %

β-Al2O3 Crystallographic Analysis: 55 %

Vitreous Phase Crystallographic Analysis : 1 %


Fused cast Alumina Block TY-M  is formed by the compact structure of α alumina and β alumina crystals in a most ideal proportion which is approximately 50% and 50% respectively,where intertwined crystals of both materials result in a very dense structure.

Specifications and applications:

--Below 1350 ℃, it has excellent corrosion resistance against molten glass and great performance against contamination to molten glass, thus it is very suitable for paving blocks and fore-hearth channel blocks.

--When in contact with molten glass, it barely produces any blistering or stones. So, α-β alumina blocks may be widely used in working tank, feeder channels, superstructures and lipstone, etc.

--In general, in soda-lime container furnaces α-β alumina fused-cast is installed in the Alcove and channel areas, as alternative to AZS fused-cast for Alcoves and as alternative to AZS fused-cast, zirmul, sinter-alumina and other sinter refractories for channels.
