The properties of fused-cast 33￣# AZS refractory with addition of a small amount of desilicated zirconium were studied.The results show that the exudation temperature of glass phase and the corrosion resistance against glass were increased.The phase composition and microstructure of the refractory were also improved.These are beneficial to manufacture the high quality glass products.
