Metalized ceramic products；Main characteristics：such products are processed by spreading a layer of metal powder to make a dense metalized cover on the ceramics，which are sealed，gas tight and stable．Usage：The product with its unique sealability may be used to make low and high vacuum switch and controlled silicon rectifier element for power networks．They can be also used to make potentiometer foundation plat, integrate circuit, refrigeration board and so on. Almost all fields including electric power, electronics, metallurgy, machinery, astronautics, aviation and military are covered.

　　Ceramics metallization, ceramics heating band and circuit board; controlled silicon crust is widely applied in hairdressing, electric mosquito-repellent incense and controlled rectifier and potentiometer.
