Nanotechnology in castable refractoryScienceDirect
· Silicon carbide (SiC) is popular among researcher as a refractory material because SiC can be stable above 2700 °C and it has high strength ( 800–1000 MPa) and fracture toughness (6–10 MPa m 1/2).It can also be used in aggressive environments due to the formation of a protective coating of SiO 2 on its surface at high temperature. SiC refractories are available as both non-oxide and
Microstructures of refractory castables prepared with sol
· Low cement and ultra low cement type castables were prepared using white fused alumina in different grades (i.e. coarse medium fine) as aggregate material and micro-fine alumina sillimanite sand micro-silica with high alumina cement as the matrix constituents.
