The Effect of Nano-magnesia Addition on the Properties of Magnesite-hercynite Refractory Bricks Made with the Use of Convertor Mud

Abstract

magnesia particles, the adequate sintering of refractory brick containing nano-magnesia take places at 1400℃. This leads to increasing of particles bonding and then, increasing mechanical strength, but it can not affect the thermal shock resistance of refractory bricks. The microstructural evaluations showed the lower porosity and further particles bonding with addition of nanomagnesia optimum content.
