This series of products are made of super calcined flint  clay and calcined bauxite,with high pressure formed and high  temperature sintered. Due to its low apparent prosity, strong  resistance to erosion and high refractoriness under load, they  are widely used in various furnaces, especially suitable to the  middle and low parts of regenerator in glass furnaces

Low Prosity Fireclay Brick for glass furnaces Features :– Low porosity  -High bulk density.  – Good Cold Crushing strength.   – High refractoriness under load.   – High mechanical strength.- Good resistance to erosion.
