Zoben Hatimi na SiC

Bayani:

Silicon Carbide yana da kyawawan halaye na juriya ga lalata, ƙarfin injina mai yawa, yawan amfani da zafi, mai kyau wajen shafa man shafawa da ake amfani da shi a matsayin fuskokin hatimi, bearings da bututu a cikin sararin samaniya, injina, ƙarfe, bugu da rini, kayan abinci, magunguna, masana'antar motoci da sauransu. Idan aka haɗa fuskokin sic da fuskokin graphite, gogayya ita ce mafi ƙanƙanta kuma ana iya yin su a matsayin hatimin injiniya waɗanda za su iya aiki a cikin mafi girman buƙatun aiki.

Babban kaddarorin Silicon Carbide:

-Ƙananan yawa

-Babban ƙarfin lantarki mai zafi (kusan aluminum)

-Kyakkyawan juriya ga girgizar zafi

-Shaidar ruwa da iskar gas

-Babban juriya (ana iya amfani da shi a 1450℃ a cikin iska da 1800℃ a cikin yanayi mai tsaka tsaki)

-Ba ya lalacewa kuma baya jika da narkewar aluminum ko zinc

-Babban tauri

-Ƙarancin ma'aunin gogayya

-Juriyar ƙazanta

-Yana jure wa acid mai ƙarfi da na asali

-Mai iya gogewa

-Babban ƙarfin injina

Aikace-aikacen Silicon Carbide:

-Hatimin inji, bearings, bearings na turawa, da sauransu

-Haɗaɗɗun da ke juyawa

-Semiconductor da shafi

-Ptalla Famfon kayan aikin

-Sinadaran sinadarai

-Madubin tsarin laser na masana'antu.

- Masu samar da wutar lantarki masu ci gaba da kwarara, masu musayar zafi, da sauransu.

Fasali
Ana samar da silicon carbide ta hanyoyi biyu:

1)Psilinda mai sintered ba tare da ressureless ba carbide

Bayan an yi wa kayan silicon carbide mai simintin da ba shi da matsi fenti, zane-zanen matakin kristal a ƙarƙashin na'urar hangen nesa ta 200X ya nuna cewa rarrabawa da girman lu'ulu'u iri ɗaya ne, kuma mafi girman lu'ulu'u bai wuce 10μm ba.

2) Rsintered silicon carbide eaction

Bayan sinadarin silicon carbide da aka haɗa da sinadarai, lu'ulu'u yana magance ɓangaren kayan da ke da santsi da laushi,
Rarrabawa da girman da ke ƙarƙashin na'urar hangen nesa ta 200X iri ɗaya ne, kuma abun ciki na silicon kyauta bai wuce kashi 12% ba.
