Low-Temperature Sintering of Iron Oxides KRAMER 1978

Abstract. To study agglomeration in iron oxides during low-temperature sintering, submicron magnetite (Fe 3 O 4) powders were processed in air and in vacuum at 773, 793, and 843 K. Specific surface area measurements were used to monitor sintering progress.Oxidation of the magnetite altered the sintering kinetics, which were dominated by surface diffusion in this temperature range.

Stability of Cementite formed from Hematite and

The stability of cementite formed during the reduction of hematite and preoxidized titano-magnetite ores in a methane-hydrogen gas mixture was examined in the temperature interval 500 C to 900 C for the hematite ore and 300 C to 1100 C for titanomagnetite. Cementite formed from hematite ore was most stable at temperatures between 750 C to 770 C.
