With suspended particles in the medium with the valve when the medium with suspended particles, the most appropriate use of its off pieces along the sealing surface of the slide valve with a wipe effect.

带有悬浮颗粒的介质用阀门当介质中带有悬浮颗粒时，最适于采用其关闭件沿密封面的滑动带有擦拭作用的阀门。

In air atmosphere, Cu2O in molten Cu corrodes Si3N4/SiC quickly. In nitrogen atmosphere or some slipcover existing, Cu corrosion resistance of Si3N4/SiC is very excellent.

在空气介质中，Si_3N_4／SiC抗侵蚀性能较差；在氮气介质中或有覆盖剂保护时，陶瓷材料具有优良的抗侵蚀性能。
