Graphite crucible inowanzo shandiswa mukugadzira simbi nezvinhu zve semiconductor. Kuti simbi nezvinhu zve semiconductor zvisvike pakuchena kwakati uye kuderedza huwandu hwetsvina, graphite powder ine kabhoni yakawanda uye tsvina shoma inodiwa. Panguva ino, zvakakosha kubvisa tsvina kubva pa graphite powder panguva yekugadzirisa. Vatengi vazhinji havazivi maitiro ekugadzirisa tsvina iri mu graphite powder. Nhasi, Furuite Graphite Editor ichataura nezvemazano ekubvisa tsvina mu graphite powder zvakadzama:
Pakugadzira upfu hwegrafiti, tinofanira kudzora zvakanyanya huwandu hwetsvina kubva pakusarudza zvinhu zvakagadziriswa, kusarudza zvinhu zvakagadziriswa zvine dota shoma, uye kudzivirira kuwedzera kwetsvina mukugadzirwa kweupfu hwegrafiti. Maoxide ezvinhu zvakawanda zvisina kuchena anogara achiora uye achipiswa nemhepo pakupisa kwakanyanya, nokudaro tichiona kuchena kweupfu hwegrafiti hunogadzirwa.
Pakugadzira zvigadzirwa zve graphized general, tembiricha yepakati pechoto inosvika pa 2300℃ uye huwandu hwetsvina yasara hunosvika pa 0.1%-0.3%. Kana tembiricha yepakati pechoto ikakwira kusvika pa 2500-3000℃, huwandu hwetsvina yasara huchaderera zvakanyanya. Pakugadzira zvigadzirwa zve graphite powder, petroleum coke ine dota shoma inowanzo shandiswa se resistance material uye insulation material.
Kunyangwe tembiricha ye graphitization ikangowedzerwa kusvika 2800℃, mamwe marara achiri kuoma kubvisa. Mamwe makambani anoshandisa nzira dzakadai sekudzikisa core yefurnace uye kuwedzera density ye current kubvisa graphite powder, izvo zvinoderedza kubuda kwe graphite powder furnace uye zvinowedzera kushandiswa kwesimba. Saka, kana tembiricha ye graphite powder furnace yasvika 1800℃, gasi rakacheneswa, senge chlorine, freon nedzimwe chlorides ne fluorides, rinoiswa, uye rinoramba richiwedzerwa kwemaawa akati wandei mushure mekukundikana kwemagetsi. Izvi zvinoitirwa kudzivirira tsvina yakapwanyika kuti isapararire mufurnace nenzira yakatarisana, uye kuburitsa gasi rakacheneswa rasara kubva mumaburi e graphite powder nekuisa imwe nitrogen.
