Alpha-beta alumina is formed by the compact structure of alpha alumina and beta alumina crystals in a most ideal proportion. It has good corrosion resistance and stability. Its feature is that when in contat with molten glass it barely produces any blistering or stones. So alpha beta alumina blocks may be widely used in the areas such as working tank feeder channels superstructures lipstone etc. To improve glass quality.
Detailed Product Description
Quick Detail:
1.Compact microstructure
2.Good erosion resistibility to molten glass
3.Good thermal shock resistibility
4.Barely rendering blister
Application:
1. α-β-Al2O3 TY-M has no contamination to glass meltdense structureexcellent corrosion resistance of glass melt below 1350°C. It is the ideal refractory materials for channels spouts and working ends of floating glass furnace.
2. β-Al2O3 TY-H has high temperaturebetter alkali resistance and excellent thermal stability measuration.It is a new refractory material of float glass furnace of breast wallPort mouth and top Crown.
3. α-Al2O3 TY-A :The typical glass contact materials for the end zones of furnaces (working-end feeder channels) when glass quality is the priority : TV Glass high quality container glass float glass.
