耐磨材料中，磁性陶瓷也是重要的組成之一，鐵氧體則是磁性陶瓷的重要代表。所謂鐵氧體，是以三價鐵離子為主要成分的氧化物的化學總稱。它的應用十分廣泛，幾乎遍及現代科學的各個領域。
除了應用于電力工業中的電機和變壓器，電子工業中的磁性元件和微波電子管，通信技術中的濾波器和傳感器，儀表工業中的電磁式儀表以及視聽裝置中的磁帶、磁頭之外，它還可以作為電磁波吸收體。
耐磨材料中還有舉足輕重的一員棗介電陶瓷。介電陶瓷的主要用途是制備儲存電能的陶瓷電容器，目前全世界每年生產的陶瓷電容器高達幾百億支，大量用于集成電路（IC）的高密度設計。此外，微波電路元件中也有大量介質陶瓷，用于制作耦合器、諧振器、濾波器等。（圖/文www.fuliido.cn）

Wear resistant materials, magnetic ceramics is also an important component of, ferrite magnetic ceramic is the important representative. The so-called ferrite, with ferric ions as the main component of the oxide chemistry. It is widely used, virtually all fields of modern science.

Wear resistant material and play a decisive role in a jujube dielectric ceramics. Dielectric ceramic is mainly used for preparing the ceramic capacitor stored energy, at present the whole world produces every year up to tens of billions of ceramic capacitor, for a large number of integrated circuit ( IC ) high density design. In addition, microwave circuit element also has a lot of dielectric ceramics, used for the production of coupler, resonator, filter.
