Creation of a Combined Liquid Phenolfomaldehyde Antioxidant-Modifier for Improving Periclase-Carbon Refractory Life

Resumo

Results are given for creation of combined antioxidants for protecting graphite from oxidation based on ethyl silicate, Al, and nickel oxalate, or based on ethyl silicate with addition of nickel sulfate (chloride) and Al. results are given for optimizing the composition for combined antioxidants based on nickel oxalate, Al, and ethyl silicate. The effect of combined antioxidant-modifiers on the properties of periclase-carbon refractory specimens containing 3% graphite is demonstrated.
