Abstract

One of the main components of periclase-carbon materials is graphite, which provides high thermal conductivity and slag resistance of refractories. However, at temperatures of 600 °C it begins to oxidize. To prevent oxidation it is proposed to modify the sol-gel graphite by composition based on nickel salts for further formation of NiO coating on its surface, which will provide additional protection. An influence of graphite amount and its modifier agent on physical and mechanical properties and slag resistance of periclase-carbon samples are investigated. It is established that graphite amount significantly affects only the strength of periclase-carbon refractories – strength of graphite decreases at increase of graphite amount from 5 to 20 %. The impact of graphite modifier agent amount on physical and mechanical properties of the samples appears on the contrary, that is by increasing the amount – properties increase. Amount of graphite and modifier agent doesn’t effect on slag resistance. We recommend the following optimal ratio of graphite in an amount of from 5 to 10 % and its modifier agent in an amount of 1,75 % for high performance periclase-carbon refractories.
