The effects of varying the amounts (5 to 30 wt%) and particle sizes of magnesium aluminate spinel (i.e. preformed and in-situ formed) incorporated in a fully dense MgO, were investigated. Mechanical properties were measured ...

The incorporation of up to 30% of spinel powder of median particle sizes 3, 11 and 22 mum into dense magnesia gives improved resistance to thermal shock as indicated both by the R''' thermal shock resistance parameters ...
