  • Behaviour of Refractory Materials for Sustainable Use in

     · Abstract With the development of boiler rooms using biomass the limitation of premature wear of refractory ceramic products by chemical corrosion became a major issue to limit the premature shutdown of the installations. In this context the French industrial technical Center for Ceramics (SFC) and its partner ICAR conducted a complete study aimed to understand the mechanisms that control

  • "Anti wetting additives for aluminosilicate refractories

    "Aluminosilicate based refractories are widely used in furnace installations for melting aluminum because they are inexpensive readily available and generally exhibit the properties desired from a refractory material. However they face severe corrosion and degradation issues due to the extremely reducing nature of molten aluminum alloys. Isothermal static cup testing is widely used as a tool

  • Impact of alternate fuels on industrial refractories and

    Residual oil is being used as an alternate fuel to natural gas and distillate oil in many industrial process heat applications. A consequence of this action is more rapid deterioration of refractories and refractory insulations due to impurities in the oil that are not present in gas and distillates.
