Abstract
Abstract Al 2 O 3 -Ti 3 AlC 2 -C refractories with different carbon content were prepared by using Ti 3 AlC 2 as substitute for partially graphite. The influences of Ti 3 AlC 2 on microstructure and thermal mechanical properties of Al 2 O 3 -Ti 3 AlC 2 -C refractories were investigated. The drastic deterioration in thermal mechanical properties of Al 2 O 3 -Ti 3 AlC 2 -C refractories was effectively prevented by reducing carbon content from 10 to 4 wt%. Particular attention was paid to the microstructure evolution of Ti 3 AlC 2 , the formations of Al 2 TiO 5 , SiAlON and Al-Si-C-O whiskers were developed to explain the limited fall in strength after thermal shock test in our works. The formation mechanism of the new bonded phases in the specimen with Ti 3 AlC 2 was explained in this paper.
