Synthesis and Conversion on Heating of Nickel-Containing Antioxidant Organic Precursor for Periclase-Carbon Refractories

The possibilities of improving the physico-mechanical properties of periclase-carbon materials by modifying the phenol-formaldehyde resin (PFR) with organoinorganic complexes are described. The composition of the modifying additives, the phase composition of the materials after the PFR hardening are given, the influence of modifiers on the formation of the structure of materials is established. It is shown that the introduction of ethyl silicate or hydrolyzed ethyl silicate into liquid PFR during preparation of the charge contributes to the formation of SiC in the phase composition. The conclusion is made about the rationality of the introduction of ethyl silicate in an amount of from 0,66 to 1 wt. % and the prospects of introducing nickel oxalate into a liquid PFR together with ammonium citrate to increase the compressive strength of periclase-carbon materials up to 60 MPa. Ill. 7. Ref. 9.
