Semicera e fana ka liaparo tse khethehileng tsa tantalum carbide (TaC) bakeng sa likarolo tse fapaneng le bajari.Semicera e etellang pele ts'ebetso ea ho roala e nolofalletsa liphahlo tsa tantalum carbide (TaC) ho finyella bohloeki bo phahameng, botsitso ba mocheso o phahameng le mamello e phahameng ea lik'hemik'hale, ho ntlafatsa boleng ba sehlahisoa sa likristale tsa SIC / GAN le likarolo tsa EPI (Sesila sa TaC se koahetsoeng ke graphite), le ho lelefatsa bophelo ba likarolo tsa bohlokoa tsa reactor. Ts'ebeliso ea tantalum carbide TaC coating ke ho rarolla bothata le ho ntlafatsa boleng ba kholo ea kristale, mme Semicera e se e rarollotse theknoloji ea tantalum carbide coating (CVD), e fihletseng boemo bo holimo ba machabeng.

2. Ho hanyetsa ho roala: The boima bo phahameng ba tantalum carbide lera le tšesaane le fana ka lesale la tataiso le ho hanyetsa ho apara hantle le ho lelefatsa bophelo ba eona ba tšebeletso.
3. Ho tsitsa ha lik'hemik'hale: Ho roala ha TaC ho na le botsitso bo phahameng khahlanong le ho senyeha ha lik'hemik'hale, ho etsa hore e tšoanelehe bakeng sa lits'ebetso mecheng ea litaba tse senyang.
4. Fokotsa likhohlano: Ho roala ha TaC ho ka fokotsa khohlano pakeng tsa lesale la tataiso ea graphite le likarolo tse ling le ho ntlafatsa katleho ea litiiso tsa mechine.
