Graphite crucible inowanzoshandiswa mukugadzirwa kwesimbi uye semiconductor zvinhu. Kuti uite simbi uye semiconductor zvinhu zvinosvika kune imwe kuchena uye kuderedza kuwanda kwetsvina, graphite powder ine high carbon content uye yakaderera tsvina inodiwa. Panguva ino, zvakakosha kubvisa tsvina kubva ku graphite powder panguva yekugadzirisa. Vatengi vazhinji havazive kubata nekusachena mu graphite poda. Nhasi, Furuite Graphite Mharidzo ichataura nezve matipi ekubvisa tsvina mugraphite poda zvakadzama:
Patinenge tichigadzira graphite powder, tinofanira kunyatsogadzirisa zvinyorwa zvetsvina kubva pakusarudzwa kwezvinhu zvakasvibirira, sarudza zvinhu zvakasvibirira zvine madota mashoma, uye kudzivirira kuwedzera kwetsvina mukugadzirisa graphite powder. Maokisi ezvinhu zvakawanda zvetsvina anogara akaora uye anoputika pakupisa kwakanyanya, nokudaro kuve nechokwadi chekuchena kweiyo inogadzirwa graphite upfu.
Paunenge uchigadzira zvigadzirwa zve graphitized, tembiricha yepakati pechoto inosvika 2300 ℃ uye yakasara yetsvina yemukati inenge 0.1% -0.3%. Kana tembiricha yepakati pechoto yakasimudzwa kusvika 2500-3000 ℃, zvirimo zvetsvina yakasara zvichadzikiswa zvakanyanya. Paunenge uchigadzira zvigadzirwa zvehupfu hwe graphite, petroleum coke ine yakaderera madota anowanzo shandiswa sechinhu chinopikisa uye zvinhu zvekudzivirira.
Kunyangwe tembiricha yegraphitization ichingowedzerwa kusvika 2800 ℃, kumwe kusvibiswa kuchiri kunetsa kubvisa. Mamwe makambani anoshandisa nzira dzakaita sekudzika kwechoto core uye kuwedzera density ikozvino kuburitsa graphite poda, izvo zvinoderedza kubuda kwegraphite hupfu hwevira uye kuwedzera simba rekushandisa. Naizvozvo, kana tembiricha yegraphite poda yevira yasvika 1800 ℃, gasi rakacheneswa, senge chlorine, freon nemamwe machloride uye fluorides, rinounzwa, uye rinoramba richiwedzerwa kwemaawa akati wandei mushure mekutadza kwemagetsi. Izvi ndezvekudzivirira tsvina ine vaporized kuti isapararira muchoto ichienda kune rumwe rutivi, uye kudzinga gasi rakacheneswa rasara kubva mumapores e graphite powder nekuunza imwe nitrogen.
