Kev Pabcuam Ntev Lub Neej SiC Coated Graphite Carrier Rau Lub Hnub Ci Wafer

Kev Pabcuam Ntev Lub Neej SiC Coated Graphite Carrier Rau Hnub Ci Wafer Featured Duab

Kev Piav Qhia Luv:

Silicon carbide yog ib hom ceramic tshiab uas muaj kev ua tau zoo thiab cov khoom siv zoo heev. Vim muaj cov yam ntxwv xws li lub zog siab thiab qhov nyuaj, tiv taus kub siab, ua kom muaj cua sov zoo thiab tiv taus xeb tshuaj lom neeg, Silicon Carbide tuaj yeem tiv taus txhua yam tshuaj lom neeg. Yog li ntawd, SiC siv dav hauv kev khawb roj, tshuaj lom neeg, tshuab thiab huab cua, txawm tias lub zog nuclear thiab cov tub rog muaj lawv qhov kev thov tshwj xeeb rau SIC. Qee qhov kev siv ib txwm peb tuaj yeem muab yog cov nplhaib foob rau lub twj tso kua mis, lub valve thiab cov cuab yeej tiv thaiv thiab lwm yam.
