Product Description:

Mullite bricks characterized with high refractoriness that can reach more than 1790C. Load softening temperature is between 1600 ~ 1700℃. Compressive strength at normal temperature is 70 ~ 260MPa. Good thermal shock resistance. 

  • Characteristics:

    Mullite brick showed good volume stability and chemical resistance. The slag will not penetrate into the mullite bricks.

    High refractoriness

    Good thermal shock resistance

    Application:

    Mainly used for top of hot blast stove, the body of blast furnace and furnace bottom, glass furnace regenerator, sintering kiln, and petroleum cracking corner lining system.

    The ideal composition and high purity of mullite brick make it available to apply in extreme conditions. Such applications are as follows:

    Chemical industry

    The glass industry

    Incinerator: highly polluted by waste and gas
