Description

R-3、R-3Ⅱare new inventive sintered materials which contains several properties, they are not only have excellent resistance on thermal shock, exfoliation, erosion; but also have high strength and very low creep rate at high-temperature (1500℃x50h≤0.1%). They are the first choice to be used in Oxy-fuel glass furnaces arches, Doghouse arches, Burner blocks, Tuck stone, etc.
