Ukusetyenziswa kakhulu kweSilicon Carbide

I-silicon carbide emnyama yenziwe ngesanti yequartz kunye ne-petroleum coke silica njengeyona nto iphambili ekrwada ngokunyibilikiswa kobushushu obuphezulu kwiziko lokumelana. Ubunzima bayo buphakathi kwe-corundum kunye nedayimane, amandla ayo omatshini aphezulu kune-corundum, kwaye i-brittle kwaye ibukhali. I-silicon carbide eluhlaza yenziwe kwi-petroleum coke kunye ne-silica njengeyona nto iphambili yemathiriyeli, enetyuwa eyongeziweyo njengesongezo, kwaye inyibilikiswa kubushushu obuphezulu kwiziko lokumelana. Ubunzima bayo buphakathi kwe-corundum kunye nedayimane, kwaye amandla ayo omatshini aphezulu kune-corundum.

Ke yeyiphi eyona nto isetyenziswayo yesilicon carbide?
1. I-Abrasives - Ikakhulu ngenxa yokuba i-silicon carbide inobulukhuni obuphezulu, ukuzinza kweekhemikhali kunye nokuqina okuthile, i-silicon carbide ingasetyenziselwa ukuvelisa i-abrasives edibeneyo, i-abrasives edibeneyo kunye nokugaya okukhululekile ukusetyenzwa kweglasi kunye neekeramics. , ilitye, isinyithi esityhidiweyo kunye nezinye izinyithi ezingenayo i-ferrous, i-carbide, i-titanium alloy, izixhobo zokusika isinyithi esinesantya esiphezulu kunye namavili okugaya, njl.

2. Izinto eziphikisayo kunye nezixhobo ezinqanda ukubola ---Ikakhulu ngenxa yokuba i-silicon carbide inendawo ephezulu yokunyibilika (iqondo lokubola), i-inertness yekhemikhali kunye nokumelana nokutshatyalaliswa kwe-thermal, i-silicon carbide ingasetyenziselwa i-abrasives kunye ne-ceramic product firing kilns. Iipleyiti ze-Shed kunye ne-saggers, izitena ze-silicon carbide zezitofu ze-cylinder distillation kwi-zinc smelting, i-aluminium electrolytic cell linings, ii-crucibles, izixhobo ezincinci zomlilo kunye nezinye iimveliso ze-silicon carbide ceramic.

3. Ukusetyenziswa kweekhemikhali-kuba i-silicon carbide inokubola kwintsimbi etyhidiweyo kwaye iphendule nge-oksijini kunye nee-oxide zetsimbi kwintsimbi etyhidiweyo ukuvelisa i-carbon monoxide kunye ne-silicon-containing slag. Ngoko ke, inokusetyenziswa njenge-arhente yokucoca kwintsimbi yokunyibilikisa, oko kukuthi, njenge-deoxidizer kunye ne-cast cast structure improver for steel making. Oku kusetyenziswa ngokubanzi i-silicon carbide yokucoca ukunciphisa iindleko. Isenokusetyenziswa njengento ekrwada ukwenza isilicon tetrachloride.

4. Izicelo zombane - ezisetyenziswa njengezinto zokufudumeza, izinto ezingenakunqanda ukuchasana kunye nezixhobo eziphezulu ze-semiconductor. Izinto ezifudumalayo ezifana ne-silicon carbon rods (ezifanelekileyo kwii-furnaces ezahlukeneyo zombane ezisebenza kwi-1100 ukuya kwi-1500 ° C), i-non-linear resistor elements, kunye neevalve ezahlukeneyo zokukhusela umbane.
