Ka tlhahiso ea butle-butle ea li-substrates tsa SiC tse tsamaisang, litlhoko tse phahameng li behoa pele bakeng sa botsitso le ho pheta-pheta ha ts'ebetso. Haholo-holo, taolo ea liphoso, phetoho e nyane kapa ho hoholeha ha lebala la mocheso sebōping, ho tla tlisa liphetoho tsa kristale kapa ho eketseha ha liphoso. Nakong ea morao, re tlameha ho tobana le phephetso ea "ho hōla ka potlako, nako e telele le e teteaneng, le ho hōla", ho phaella ntlafatsong ea khopolo le boenjiniere, re boetse re hloka lisebelisoa tse tsoetseng pele tsa tšimo ea mocheso e le tšehetso. Sebelisa lisebelisoa tse tsoetseng pele, holisa likristale tse tsoetseng pele.
Tšebeliso e sa nepahalang ea lisebelisoa tsa crucible, tse kang graphite, porous graphite, tantalum carbide powder, joalo-joalo sebakeng se chesang se tla lebisa mefokolo e kang ho eketseha ha carbon. Ho phaella moo, lits'ebetsong tse ling, ho phunyeletsa ha graphite ea porous ha hoa lekana, 'me likoti tse eketsehileng lia hlokahala ho eketsa ho phunyeletsa. Graphite e nang le porous e nang le matla a holimo e tobane le mathata a ho sebetsa, ho tlosoa ha phofo, etching joalo-joalo.
VET e hlahisa moloko o mocha oa SiC kristale e ntseng e hola e futhumatsang thepa, porous tantalum carbide. Moqapi oa lefats'e.
Matla le boima ba tantalum carbide li phahame haholo, 'me ho etsa hore e be porous ke phephetso. Ho etsa porous tantalum carbide ka porosity e kholo le bohloeki bo phahameng ke phephetso e kholo. Hengpu Technology e phatlalalitse katleho e kholo ea tantalum carbide e nang le porosity e kholo, e nang le porosity e phahameng ea 75%, e etellang lefatše pele.
Filtration ea karolo ea khase, ho lokisoa ha mocheso oa sebaka sa mocheso, tataiso ea phallo ea thepa, taolo ea ho lutla, joalo-joalo, e ka sebelisoa. E ka sebelisoa le e 'ngoe e tiileng ea tantalum carbide (compact) kapa tantalum carbide coating ho tloha Hengpu Technology ho theha likarolo tsa sebaka sa heno tse nang le phallo e fapaneng ea ho phalla.
Likarolo tse ling li ka sebelisoa hape.
