Zirconia Refractory Tile
Zirconia refractory tiles are precision-fired ceramic tiles with high zirconia content for lining glass melting tanks and petrochemical reactors. They resist molten glass corrosion and thermal cycling. HTS 6902.90.50 covers these as other refractory tiles, not siliceous earths.
