Niobium Disc Description
Niobium discs thiab niobium lub hom phiaj yog dav siv nyob rau hauv cov tshuaj, ships, kua siv lead ua zaub (LCD) thiab conductive txheej kev lag luam, thiab lwm yam. Peb muab niobium disc & lub hom phiaj ib qhov kev thov, machining txheej txheem kuj yuav nqa tawm ib tug kos duab. Niobium hlau disc yog txiav los ntawm daim ntawv lossis phaj, nws tuaj yeem ua los ntawm niobium thaiv lossis ingot yog tias cov tuab loj. Thicker disc yuav raug hu ua lub tog raj kheej, thaiv, thiab lwm yam.
