As a new material, the new ceramic-based friction material can effectively improve the safety and stability of automobile braking, and is gradually applied to the brake pads of automobiles. At present, the research on ceramic tribology at home and abroad mainly focuses on a few ceramic materials such as SiC, Si3N4, Al2O3, BN and ZrO2. Among them, C/C-SiC composite materials and Al2O3 ceramic friction materials are the most widely used. Ceramic-based brake pads are popular because of their many excellent properties, especially they have good corrosion resistance and durability. They are clean and environmentally friendly products with stable performance, and will not produce A lot of noise, so it can ensure people's driving comfort.

The addition of zirconium silicide can increase the wear resistance and high temperature resistance of the material, carbon ceramic brake pads, and brake discs. The mass fraction of zirconium disilicide is 10-15%. Adding this mass fraction of zirconium disilicide into the ceramic matrix composite material can significantly reduce the sintering temperature of the material preparation.
