Jun 18 2015 · (9) Refractory brick linings are a must for satisfactory lining life in large crucibles. Double brick linings have been successfully employed in Latrobe s 7.5 15 and 30-ton crucibles since 1964. Refractories most widely used today are of the mag- nesia-spine1 type high magnesia bonded with alumina or of the high alumina variety.

The challenges on its wider use are very much the same in this regard as are those on vanadium. Normalized and control-rolled plate steels used for heavy equipment and thick-walled structures including offshore platforms benefit from columbium s ability to maintain fine grain size and improve strength while retaining high toughness.

Refractory minerals would need highly corrosive leachants and aggres- sive conditions of leaching such as those obtained at elevated temperatures and pressures as in autoclaves. If the structural features show the substitution of one element at the lat- tice sites of another then separating these elements by physical methods is not possible.
