In this paper,phase composition and thermal expansion behaviour of CaO stabilised ZrO 2 refractory were studied.Special attention was paid to the expansion behaviour of three materials with different phase composition.These research results indicated that the expansion behaviour could be improved,thus leading to the increase in the thermal shock resistance of CaO stabilised ZrO 2 refractory,by modifying the stabilisation of ZrO 2,which possibly also enhanced the erosion resistance of the obtained material.
