Abstract

Abstract: A novel lightweight adiabatic refractory material combining alkaline earth silicate (AES) fiber board and SiC particles was fabricated by immersing the AES fiber board into a slurry consisting of SiC particles with a median diameter of 1.2 μm and 13% silica-sol as an inorganic binder. When the composite was heated at 1400 °C for 8 h, the fired shrinkage of the composite was almost 0%, while that of untreated AES fiber board was 3.2%. The compressive strength of the composite heated at 1300 °C for 8 h was greatly improved to 0.95 MPa, 4.6 times that of untreated AES board. The corrosion resistance of the composite to a mixture of iron (II) oxide and sodium carbonate at 1400 °C was improved by more than 40% compared to that of untreated AES fiber board.
