Izakhiwo kanye nokusetshenziswa okuyinhloko kwe-silicon carbide e-reaction-sintered

Izakhiwo ze-silicon carbide ezihlanganisiwe kanye nokusetshenziswa okuyinhloko? I-Silicon carbide ingabizwa nangokuthi i-carborundum noma isihlabathi esingashi, iyinhlanganisela engaphili, ehlukaniswe i-silicon carbide eluhlaza kanye ne-silicon carbide emnyama. Uyazi yini izakhiwo kanye nokusetshenziswa okuyinhloko kwe-silicon carbide? Namuhla, sizokwethula izakhiwo kanye nokusetshenziswa okuyinhloko kwe-silicon carbide.

I-silicon carbide e-reactive sintering iwukusetshenziswa kwesihlabathi se-quartz, i-coke ye-petroleum e-calcined (noma i-coking yamalahle), i-slag yokhuni (ukukhiqizwa kwe-silicon carbide eluhlaza kudinga ukwengeza usawoti wokudla) nezinye izinto zokusetshenziswa, ngokusebenzisa ukuncibilikisa okushisayo okuqhubeka nokushisa okuphezulu.

Izakhiwo ze-silicon carbide e-reaction-sintered:

1. Ukuqhuba ukushisa kanye ne-coefficient yokwandisa ukushisa ye-silicon carbide. Njengohlobo lwezinto eziphikisayo, izitini ezenziwe nge-carbon zinokumelana okuhle kakhulu nokushaqeka. Lokhu kubonakala kakhulu ekuqhubeni ukushisa okunamandla (i-coefficient yokudlulisa ukushisa) kanye ne-coefficient ephansi yokwandisa ukushisa.

2, ukuhanjiswa kwe-silicon carbide. I-Silicon carbide iyinto ye-semiconductor, ukuhanjiswa kwayo kuyahlukahluka ngohlobo kanye nenani lokungcola okufakwa ku-crystallization, futhi ukumelana kuphakathi kuka-10-2-1012Ω·cm. Phakathi kwazo, i-aluminium, i-nitrogen kanye ne-boron kunethonya elikhulu ekuhanjisweni kwe-silicon carbide, futhi ukuhanjiswa kwe-silicon carbide ene-aluminium eningi kukhula kakhulu.

3. Ukumelana kwe-silicon carbide. Ukumelana kwe-silicon carbide kuyashintsha ngokushintsha kwezinga lokushisa, kodwa ngaphakathi kobubanzi obuthile bokushisa kanye nezici zokushisa ze-resistor yensimbi ziyaguqulwa. Ubudlelwano phakathi kokumelana nokushisa kwe-silicon carbide buyinkimbinkimbi kakhulu. Ukuqhuba kwe-silicon carbide e-reaction-sintered kuyanda ngokushisa okukhuphukayo kuya enanini elithile, futhi ukuqhuba kwe-conductivity kwehla lapho izinga lokushisa likhuphuka futhi.

Ukusetshenziswa kwe-silicon carbide:

1, izinto ezingagugi – ezisetshenziswa kakhulu ukwenza isondo lesihlabathi, iphepha lokusila, itshe eligobile, isondo lokugaya, unamathisele wokugaya kanye nemikhiqizo ye-photovoltaic kumaseli e-photovoltaic, amaseli e-photovoltaic kanye nezingxenye zokugaya, ukugaya kanye nokupholisha ubuso.

2, izinto eziphikisayo eziphezulu – zingasetshenziswa njenge-deoxidizer yemboni yensimbi kanye nezinto ezingamelana nokugqwala, ukwenza izingxenye ezilungiselelwe kusengaphambili ze-oven yokushisa okuphezulu, izingxenye eziqinile, njll.

3, izinto zobumba ezisebenzayo – azigcini nje ngokunciphisa umthamo wesitofu, kodwa futhi zithuthukisa ikhwalithi yemikhiqizo yesitofu sezimboni, zinciphise isikhathi sokujikeleza, ziyinto efanelekile engaqondile yokushiswa kwe-ceramic glaze, izinto zobumba ezingezona i-oxide eziqhubekayo ezishisayo, ezibonisa i-porcelain eshisiwe.

4, izinsimbi ezingavamile - amabhizinisi ensimbi nensimbi, insimu yokugxila embonini yensimbi, inohlelo oluthile lokusebenza.

5, okunye – okusetshenziselwa ukwenza ungqimba lwemisebe ye-infrared ekude noma ipuleti le-silicon carbide dryer yemisebe ye-infrared ekude.

I-silicon carbide ngenxa yezakhiwo zayo zamakhemikhali ezibushelelezi, i-coefficient ephezulu yokudlulisa ukushisa, i-coefficient encane yokukhulisa eqondile, ukumelana okuhle nokuguguleka, ngaphezu kwezinto ezingaguguleki, kunezinye izindlela ezisetshenziswa kakhulu, njengokuthi: ngenqubo entsha yokufaka i-silicon carbide powder glue ku-centrifugal impeller noma i-cylinder body cavity, ingathuthukisa ukumelana nokuguguleka futhi yandise impilo yenkonzo izikhathi ezi-1 kuya kwezi-2; Isetshenziselwa ukwenza izinto eziphikisayo zezinga eliphezulu, ukumelana nokushaqeka okushisa okuphezulu, usayizi omncane, isisindo esincane namandla aphezulu, ukuvikelwa kwemvelo kanye nomphumela wokonga amandla kusobala. I-silicon carbide yezinga eliphansi (equkethe cishe i-85% SiC) iyi-ejenti enhle yokususa i-oxidizing, engasetshenziswa ukusheshisa izinga lokwenza insimbi, futhi ilungele ukuphatha ukwakheka nokuthuthukisa ikhwalithi yensimbi. Ngaphezu kwalokho, i-silicon carbide isetshenziselwa futhi ukwenza izinto eziningi zokushisa zikagesi i-silicon molybdenum rod.
