| Abstract: | Department of Materials and Engineering,Tsinghua University,Beijing 100084,ChinaZrO 2 -mullite multiphase refractories were prepared via a novel process route,where coarse mullite particles were bonded by reaction sintering products of ultrafine ZrSiO 4 and Al 2 O 3 powders.The preparation process,microstructure,mechanical property and thermal shock resistance of the refractories were investigated.The obtained material possesses a high density and good thermal shock resistance simultaneously. |
