Abstract

Periclase-carbon granules consisting of a core of granular periclase powder and a shell (case) containing graphite, periclase, additives, and an organic binder form during the process of body preparation. The specific surface of the granules decreases with increasing diameter of the granules. After calcination at 1000°C, the specific surface of the granules increases by approximately an order of magnitude. The magnetic fraction obtained from the crushed (milled) granules contains the maximum quantity of graphite and, consequently, the maximum extent of carbon burn-ups is observed in this fraction. It is advisable to use the periclase-carbon granules for the pressed, rammed, and vibrated bodies and for the products, blocks, and monolithic linings of various thermal units.
