One Of High Level Metals Silicon Carbide

The microwave absorption characteristics of silicon carbide mesh ceramics are almost more than two times higher than that of solid materials, and the improvement of this absorption performance mainly comes from the attenuation caused by the reflection, scattering and interference of electromagnetic waves produced by the mesh structure. The effects of pore size, relative density and sample thickness on the microwave absorption performance of silicon carbide mesh ceramics are discussed. This work will provide a new approach for the design of low-cost, high-performance structural microwave absorbing materials.

1.Preparation method of high-hardness, high-wear-resistant carbon self-doped silicon carbide semiconductor film, relates to the field of semiconductor technology, the cleaning equipment comprises an ultrasonic cleaning groove and a hanging basket matched with the ultrasonic cleaning groove, the front and back sides of the ultrasonic cleaning groove are fixedly connected with a fixing plate, the front of the ultrasonic cleaning groove is fixedly connected with a mounting plate, a driving mechanism is arranged on the mounting plate, and a shaking mechanism that is used in conjunction with the driving mechanism to drive the hanging basket to shake is arranged on the fixed plate, Through the mutual cooperation of the driving mechanism and the shaking mechanism, after the substrate is cleaned by ultrasonic, the hanging basket is jacked up and shaken back and forth, so that the liquid medicine remaining on the substrate material can be treated, and the substrate is taken out to reduce the pollution to the surrounding environment.
