Ib nrab hli ib feem nrog Tantalum Carbide txheej

Lus piav qhia luv luv:

Graphite yog nrov raws li ib qho zoo heev kub resistant cov ntaub ntawv nyob rau hauv kub kub ib puag ncig.Txawm li cas los xij, graphite yog nquag oxidation ntawm qhov kub thiab txias, uas tsis tuaj yeem zam tau txawm tias nyob hauv lub tshuab nqus tsev nrog cov roj inert.Txhawm rau daws qhov teeb meem no, Semicera tau tshaj tawm CVD tantalum carbide (TaC) txheej khoom los muab kev tiv thaiv zoo rau graphite substrates.Peb CVD tantalum carbide (TaC) txheej tuaj yeem tiv thaiv graphite oxidation zoo thiab muab kev kub siab tiv thaiv piv rau graphite.Tsis tas li ntawd, TaC yog cov khoom siv tsis zoo uas tuaj yeem tiv thaiv cov pa roj xws li argon thiab hydrogen ntawm qhov kub thiab txias.Tham Semicera tam sim no kom paub ntau ntxiv txog peb cov tantalum carbide CVD coated EPI susceptors kom muaj kev ruaj ntseg thiab kev ntseeg siab ntawm koj cov ntawv thov kub.

Product Detail

Khoom cim npe

TaC txheej yog ib hom tantalum carbide (TaC) txheej npaj los ntawm lub cev vapor deposition tshuab, nws muaj cov yam ntxwv hauv qab no:

1. High hardness: TaC txheej hardness yog siab, feem ntau muaj peev xwm ncav cuag 2500-3000HV, yog ib qho zoo heev txheej txheej.

2. Hnav tsis kam: TaC txheej yog hnav-resistant, uas tuaj yeem txo qhov hnav thiab kev puas tsuaj ntawm cov khoom siv kho tshuab thaum siv.

3. Zoo kub tsis kam: TaC txheej kuj tuaj yeem tswj nws qhov kev ua tau zoo nyob rau hauv qhov kub thiab txias.

4. Kev ruaj ntseg tshuaj zoo: TaC txheej muaj tshuaj lom neeg ruaj khov thiab tuaj yeem tiv taus ntau yam tshuaj lom neeg, xws li cov kua qaub thiab cov hauv paus.
