I-Silicon Carbide Ceramic

I-Reaction Bonded Silicon Carbide

Iimveliso ze-silicon carbide ezibotshelelweyo ze-reaction ziye zenzelwe amandla afanelekileyo kunye nokumelana nokugqwala. Iingenelo zokusebenzisa i-silicon carbide ebotshelelweyo ze-reaction ziquka: ukumelana nokuguguleka okugqwesileyo, ubomi obude ngenxa yokumelana kwayo okugqwesileyo ne-oxidation, ukumelana nokutsha kobushushu okugqwesileyo, kunye nokukwazi kwayo ukumila okuntsonkothileyo okukhulu okanye okuncinci.

I-Nitride Bonded Silicon Carbide

I-silicon carbide ebotshelelwe yi-silicon nitride yenzelwe ukumelana nokuguguleka okugqwesileyo. Inokwenziwa ibe ziimo ezintsonkothileyo kakhulu ngenxa yeempawu zayo eziphoswayo kwaye ikwanazo neepropati ezinqwenelekayo zokuchasana nokuguguleka kunye neekhemikhali. Ukusetyenziswa kwayo okuphambili kuya kuba apho kufuneka ukumelana nokuguguleka okuphezulu okanye apho imo intsonkothile kakhulu ukuba yenziwe kwezinye iingxubevange. Iinguqulelo eziphindwe kabini ezine-porosity evulekileyo encinci kunye nokumelana nokuguguleka kwe-oxidation nazo ziyafumaneka.

I-Silicon Carbide eSintered

I-sintered alpha silicon carbide iveliswa yi-sintering ultra-pure submicron powder. Le powder ixutywe nezixhobo zokusinyisa ezingezizo i-oxide, emva koko yenziwe ibe ziimo ezintsonkothileyo ngeendlela ezahlukeneyo kwaye idityaniswe yi-sintering kubushushu obungaphezulu kwama-3632°F.

Inkqubo yokusila iphumela kwi-silicon carbide ene-fine-grained single-phase ecocekileyo kakhulu kwaye ifanayo, engenazo iimbobo ezivumela izixhobo ukuba zikwazi ukumelana neendawo ezirhabaxa, iindawo ezirhabaxa, kunye neendawo ezisebenza phantsi kobushushu obuphezulu (2552°F). Ezi mpawu zenza i-sintered alpha silicon carbide ilungele ukusetyenziswa njengee-chemical and slurry pump seals kunye nee-bearings, ii-nozzles, i-pump kunye ne-valve trim, amaphepha kunye nee-textile components, kunye nokunye.
