| Abstract |
| Using Orissa chrome ore, A/mora magnesite and Salem magnesite several chromemagnesite
and magnesite-chrome compositions were prepared and fired to temperatures
between 1400°C-1700°C. Physical and refractory properties of the fired specimens
were studied. The microstructure was examined in detail. Good direct bonding between
chromite and periclase grains developed at 1700°C. The extent of direct bonding was
more pronounced in compositions containing larger amount of monticellite in the matrix. |
