Unfired periclase-carbon refractories with a thermoreactive polymer binder

Elevated environmental requirements necessitate the development of new binders with a high carbon residue, heat treatment of which does not result in emission of toxic or carcinogenic substances. Such binders should have adequate technological properties. It is shown that it is possible to use a thermoreactive polymer binder based on a resorcinol oligomer for production of periclase-carbon refractories. The binder is soluble in water and organic solvents and possesses a high carbon residue (> 60%). Specimens of periclase-carbon refractories with the suggested binder and 5–12% graphite exhibit good ceramic and mechanical properties.
