JOURNAL RESTRICTED ACCESSWe investigated changes in pore morphology from measurements of gas permeability, apparent porosity and pore size distribution of MgO-C bricks controlled relative density. Apparent porosity of the MgO-C bricks with increased its relative density was decreased and were decreased gas permeability, too. Also, with decreasing of average pore size, MgO-C bricks were decreased its permeability. These results suggested for the first time that a pore morphology formed in MgO-C bricks is largely involved. The fractal dimension of the pores was increased with increasing the relative density of MgO-C bricks. This fact indicated that fragmentation of pore and diffusion of fragmented pores in MgO-C bricks were produced through the formation processes of the refractory texture.View full abstractDownload PDF (1954K)
