Umsesane wokutywina we-SiC

Inkcazo:

I-Silicon Carbide inepropathi ye-resistant-corrosion egqwesileyo, amandla omatshini aphezulu, ukugcwala okuphezulu kwe-thermal, ukuthambisa okulungileyo okusetyenziselwa njengobuso betywina, iibheringi kunye neetyhubhu kwisiphekepheke, oomatshini, isinyithi, ukushicilela kunye nokudaya, ukutya, amayeza, ishishini lemoto njalo njalo. Xa ubuso be-sic zidityaniswe nobuso begraphite ukukhuhlana yeyona nto incinci kwaye ingenziwa ibe ngamatywina omatshini akwazi ukusebenza kwiimfuno eziphezulu zokusebenza.

Iipropati zeSilicon Carbide eziSisiseko:

-Ukuxinana okuphantsi

-I-thermal conductivity ephezulu (kufuphi ne-aluminium)

-Ukumelana kakuhle nokothuka kwe-thermal

-Ubungqina bolwelo kunye negesi

-I-refractoriness ephezulu (inokusetyenziswa kwi-1450 ℃ emoyeni kunye ne-1800 ℃ kwindawo engathathi hlangothi)

-Ayichatshazelwa ngumhlwa kwaye ayimanzi nge-aluminium enyibilikisiweyo okanye i-zinc enyibilikisiweyo.

-Ukuqina okuphezulu

-I-coefficient yokukhuhlana okuphantsi

-Ukuxhathisa i-abrasion

-Uxhathisa kwii-asidi ezisisiseko kunye nezomeleleyo

-Iyaphucuka

-Amandla omatshini aphezulu

Isicelo seSilicon Carbide:

-Izitywina zoomatshini, iibheringi, iibheringi zethrust, njl

-Amalungu ajikelezayo

-Semiconductor kunye nokwaleka

-Piintengiso Pump amacandelo

-Amacandelo amachiza

-Izibuko zeenkqubo zelaser zoshishino.

- Ii-reactors ezihamba ngokuqhubekayo, abatshintshi bobushushu, njl.

Uphawu
I-silicon carbide yenziwe ngeendlela ezimbini:

1)Pi-silicon carbide engaqinisekanga

Emva kokuba kufakwe i-silicon carbide impahla engenaxinzelelo, i-crystal phase diagram phantsi kwe-200X optical microscope ibonisa ukuba ukuhanjiswa kunye nobukhulu beekristali zifana, kwaye i-crystal enkulu ayidluli i-10μm.

2) Reaction sintered silicon carbide

Emva kokuba i-silicon carbide isabela ngokwekhemikhali iphatha icandelo elisicaba kunye neligudileyo lezinto, ikristale
ukusabalalisa kunye nobukhulu phantsi kwe-microscope ye-200X ebonakalayo ifana, kwaye umxholo we-silicon wamahhala awudluli kwi-12%.
