RT-41 is the Alumina-Zirconia-Sillica fused cast material bearing＞40% ZrO2.
It has a much higer ZrO2 content ,reduced amount of glass phase and dense structre with interlocking of zirconia and eutectoid crystais,resulting in excellent corrosion resistance and relatively low bubbie rate to moiten glass at high temperature.
It is suitable for the key portion where the corrosion is serious in the glass furnace.
