Progress on Preparation of Refractory Powder Using Nonmetallic Minerals and Its Applications

摘要

This review summarized the recent advances in the utilization of nonmetallic minerals and their applications for fabrication of unfired refractories. The preparation of refractory powder utilizing cheap nonmetallic minerals of zircon,low-grade bauxite and quartz was discussed,respectively. The preparation of three unfired SiC-based refractories: SiC- SiAlON- ZrN, Al2O3- SiC /β-SiAlON / Ti( C,N)- C,and Al2O3- SiC- Si3N4 using the as-prepared refractory powders was introduced.
