I-silicon carbide exutywe ne-reaction-sintered: lukhetho oludumileyo lwezixhobo ezishushu kakhulu

Kwizicelo zobushushu obuphezulu, ukukhetha izinto kubalulekile. Phakathi kwazo, izinto ze-silicon carbide ezifakwe kwi-reaction-sintered ziye zaba lukhetho oludumileyo ngenxa yokusebenza kwazo okugqwesileyo. I-silicon carbide efakwe kwi-reaction-sintered sisixhobo se-ceramic esenziwe ngokusila kwe-carbon kunye ne-silicon powder kumaqondo obushushu aphezulu.

Okokuqala, i-reac-sintered silicon carbide inozinzo oluhle kakhulu kubushushu obuphezulu. Iyakwazi ukugcina amandla ayo oomatshini kunye nozinzo lweekhemikhali kubushushu obuphezulu obufikelela kwi-2,000 degrees Celsius. Oku kuyenza ifaneleke kakhulu kwiindlela zokusetyenziswa kubushushu obuphezulu, njengakwimizi-mveliso yokucoca ioyile, intsimbi kunye ne-ceramic.

Okwesibini, i-reac-sintered silicon carbide inokumelana nokuguguleka okuhle kakhulu. Le nto inokumelana nokuguguleka okuhle kakhulu kwaye inokuhlala izinzile ixesha elide kwiimeko ezinzima zokungqubana nokuguguleka. Ke ngoko, isetyenziswa kakhulu kwiindawo zokugaya, ukusika kunye nezixhobo zokurhawuzelela.

Ukongeza, i-reac-sintered silicon carbide ikwanayo ne-thermal conductivity egqwesileyo kunye ne-chemical inertia. Ingaqhuba ubushushu ngokukhawuleza kwaye ibonise ukumelana okuhle nokugqwala kwiindawo ezigqwalisayo ezifana ne-asidi kunye ne-alkali. Oku kuyenza isetyenziswe kakhulu kwishishini leekhemikhali kunye nolawulo lobushushu.

Kufuneka kuqatshelwe ukuba inkqubo yokulungiselela i-reaction-sintered silicon carbide iyinkimbinkimbi, ifuna ubushushu obuphezulu kunye neemeko ezikhethekileyo zokusabela. Nangona kunjalo, ngenkqubela phambili eqhubekayo yetekhnoloji, inkqubo yemveliso iye yaphuculwa kancinci kancinci, nto leyo eyenza ukuba ixabiso lezinto ezisetyenzisiweyo linciphe kancinci kancinci, kwaye ikhuthaza ukusetyenziswa kwayo ngokubanzi kwiinkalo ezahlukeneyo.

Ngamafutshane, njengesixhobo sobushushu obuphezulu, i-reaction-sintered silicon carbide lukhetho olufanelekileyo kwiindlela ezininzi zobushushu obuphezulu ngenxa yozinzo lwayo oluhle kakhulu lobushushu obuphezulu, ukumelana nokuguguleka, ukuqhuba kobushushu kunye ne-inertia yamakhemikhali. Njengoko iteknoloji iqhubeka nophuhliso, sinokulindela ukuba i-reaction-sintered silicon carbide isetyenziswe kwiindawo ezininzi kunye nophuculo oluthe kratya lokusebenza.
