Niobium Crucible Description
Raws li ib tug ntshiab hlau, niobium yog heev reactive thiab tsim ib tug heev ruaj khov oxide thaum raug rau huab cua uas txhim khu nws corrosion kuj. Niobium yuav hnov mob nrog ntau yam tsis yog hlau ntawm qhov kub siab.
Niobium crucibles (niobium khob) yog siv nyob rau hauv metallurgical kev lag luam, tshuaj lom neeg kev lag luam, machinery processing, iav, thiab ceramic industries.
SSC tshwj xeeb hauv kev muab niobium crucibles nrog ntau yam duab xws li puag ncig, tapered, square, rectangular, cylindrical, nkoj, thiab lwm yam. Kev cai configurations muaj.
