(Ngaba iSilicon Nitride iyabiza?)

I-Silicon nitride yinto eyomelele kakhulu, enobulukhuni obuphezulu obuxhathisa kakhulu ekudlekeni kunye nokunxiba. Ukomelela kwayo koomatshini kukwayenza ikwazi ukumelana namaqondo obushushu aphezulu. Ifanelekile kwiindawo zokunxiba eziphezulu, ezinje nge blade ze turbine kunye neeshaft ezichanekileyo. Iphinde ixhathise kwiintsimbi ezingenayo i-ferrous, iyenza ifaneleke kwizicelo zobushushu obuphezulu.

I-Silicon nitride nayo i-bioinert, evumela ukuba isetyenziselwe ukufakelwa kwe-biomedical. Ngasekupheleni kweminyaka yee-1980, izazinzulu zaqinisekisa ukuba izinto zazinokuhambelana nezilwanyana xa zifakwe kwizilwanyana. Uphononongo lwe-1999 luqinisekisile oku kufunyanisiweyo, ebonisa ukuba i-silicon nitride i-biocompatible ngokwaneleyo kwi-in vitro yokusasazwa kweeseli zethambo.

Kukho iintlobo ezimbini eziphambili ze-silicon nitride. Eyokuqala yi-silicon nitride ecinezelekileyo, esetyenziselwa izixhobo zokusika. Uhlobo lwesibini, i-sintered reaction-bonded silicon nitride, iphucule ukuxhathisa impembelelo kunye nokuqina. Oku kubandakanya ukudibanisa i-silicon nitride kwigraphite kwaye emva koko i-sintering kumaqondo obushushu aphezulu okanye uxinzelelo.

I-Silicon nitride yimathiriyeli eyomelezwayo ene-athom ephezulu yokudibanisa amandla. Ngenxa yoko, iyaxhathisa ngokugqithisileyo ekudlekeni kuzo zombini izisombululo ezineasidi kunye nezisisiseko. Oku kwenza kube lukhetho oludumileyo kwizicelo zesakhiwo kumashishini ahlukeneyo. Ikwayimpahla egqwesileyo yokumelana nokunxiba kunye nobushushu obuphezulu.

I-Silicon nitride iphezulu kwi-corrosion kunye ne-thermal shock resistance xa kuthelekiswa ne-high-grade steel. I-silicon nitride ingasetyenziselwa kwiibheringi kuba ilula kunentsimbi. Ubuninzi bayo obuphantsi buyenza ibe lula njenge-aluminiyam, inciphisa uxinzelelo lwe-centrifugal kwiintlanga zangaphandle.

Unokwenza amacandelo amaninzi ahlukeneyo kwi-silicon nitride. I-Precision Ceramics igcina uluhlu olubanzi lweentonga ze-silicon nitride zeceramic ezinomphezulu ogqwesileyo. Ezi ntonga zilungele amacandelo enjini, ipistons, iibheringi kunye nezinye izicelo. Inkampani ibonelela ngokugqibeleleyo komatshini / amandla okugaya ukuvelisa iinxalenye ze-silicon nitride zesiko.

I-Silicon nitride yimathiriyeli yolwakhiwo lweceramic eyenziweyo. Isebenza kunye ne-nitrogen okanye ezinye iikhompawundi ze-organic kunye nabathwali be-silicon kunye ne-ammonia. Yaqala ukufunyanwa phakathi kwenkulungwane ye-18 kodwa kwakungekho lula ukuyivelisa de kube kamva. Emva kwexesha, i-covalent ye-silicon kunye ne-nitrogen ikhokelele kuphuhliso lweentlobo ezimbini eziphambili ze-silicon nitride: i-silicon nitride ye-sintered kunye ne-reaction-bonded silicon nitride.

I-Silicon nitride yiceramic yobunjineli ebalulekileyo esetyenziswa kwizicelo ezininzi ezahlukeneyo. Nangona ubushushu bayo buphezulu, ineempawu ezibalaseleyo zoomatshini kunye neekhemikhali. Yimpahla egqwesileyo yokwenza i-capacitors kwiichips ze-analog. I-silicon nitride ikwasetyenziswa kwizicelo ze-biomedical.

Obona bunzima bomaleko we-nitride buxhomekeke kwiphedi kunye nobukhulu be-oksidi yasendle. Umaleko omde we-nitride wonyusa uxinzelelo lomatshini kwi-silicon ngexesha le-oxidation yasendle. Ukuba olu xinzelelo ludlula imida ebalulekileyo, lunokubangela ukuchithwa, okukhokelela kumasango e-transistor avuzayo. Ubukhulu obuphezulu bomaleko we-nitride kufuneka bube phakathi kwe-150 nm ukuya kwi-200 nm. Ngexesha elifanayo, ubukhulu be-pad oxide kufuneka bube phakathi kwe-10 nm ukuya kwi-20 nm.
