耐磨材料中，磁性陶瓷也是重要的组成之一，铁氧体则是磁性陶瓷的重要代表。所谓铁氧体，是以三价铁离子为主要成分的氧化物的化学总称。它的应用十分广泛，几乎遍及现代科学的各个领域。
除了应用于电力工业中的电机和变压器，电子工业中的磁性元件和微波电子管，通信技术中的滤波器和传感器，仪表工业中的电磁式仪表以及视听装置中的磁带、磁头之外，它还可以作为电磁波吸收体。
耐磨材料中还有举足轻重的一员棗介电陶瓷。介电陶瓷的主要用途是制备储存电能的陶瓷电容器，目前全世界每年生产的陶瓷电容器高达几百亿支，大量用于集成电路（IC）的高密度设计。此外，微波电路元件中也有大量介质陶瓷，用于制作耦合器、谐振器、滤波器等。（图/文www.cddnvga.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.
