EFFECTS OF RAW MATERIAL PROPERTIES AND Fe₂O₃ ADDITIONS ON THE SINTERING OF DOLOMITES.

Dolomite is a refractory raw material with the ideal composition of CaCO//3-MgCO//3. It is usually found associated with varying amounts of accessory oxides. Four high purity dolomites of different origin were densified by the calsintering process. The intrinsic sinterability is most affected by the iron oxide content and porosity, whereas the densification of the Fe//2O//3 doped dolomites are primarily affected by the aggregate size.
