Ingabe ukhona umehluko phakathi kwezitini ezilungiswe nge-silicon kanye isitini esibomvu esilungiswe nge-silicon?

Kunamabanga amathathu ahlukene ezitini ze-silica-mo, 1550, 1650 kanye ne-1680. Asetshenziswa endaweni yoguquko yezitini zikasimende ezijikelezayo ezinosayizi abahlukene.

Uma kuqhathaniswa nezitini ezibunjwe nge-silica, izitini ezibomvu ze-silico-mold ziminyene, zinamandla acindezelayo angcono nokumelana nokugqwala, futhi zinempilo ende yesevisi. Isetshenziswa endaweni yenguquko yamakhilni amakhulu usimende.

Njengoba umjikelezo wempilo wezitini ze-alkaline ezisetshenziswa endaweni yokushisa ephezulu yeziko elikhulu likasimende liya liba lide futhi lide, ukuze kwandiswe impilo yesevisi yendawo yoshintsho. Ngokwesimo sangempela esisetshenziswayo, umenzi wenze izitini eziguquguqukayo ze-silicon molybdenum nezitini ze-silicon corundum, ezikwazi ukumelana nokuguga futhi ezimelana nokugqwala.

Okuqukethwe kwe-silicon carbide yesitini esibunjwe nge-silicon kuncane kunesitini esibomvu esibunjwe nge-silicon, futhi ukuminyana komzimba waso namandla nakho kuphansi. Izitini eziguquguqukayo ezibunjwe nge-silicon nezitini ze-silicon corundum zisezingeni eliphezulu nekhwalithi kunesitena esibomvu esibunjwe nge-silicon kanye nesitini esibunjwe nge-silicon.

Izitini ze-silica corundum zingasetshenziswa endaweni evuthayo yama-lime rotary kilns, futhi zingasetshenziswa olwelweni lwama-zinc volatilization kilns.

Iphuzu lokumelana nezitini ze-silicon molybdenum ukumelana nokuhuqwa, ukumelana nokuguguleka, ukumelana nokukhathala kanye nokwakheka kwendandatho. Inqubo ye-sintering iyinkimbinkimbi kakhulu kunaleyo yezitini eziphakeme ze-alumina.

Njengoba izitini ze-silicon carbide zidinga ukungeza ingxenye ethile ye-silicon carbide, ubulukhuni kanye nezithako ezitholakala ezintweni ezingavuthiwe kuzokwenza isitini sibonakale sibomvu futhi simnyama, futhi umbala omnyama we-cyan ukusabela kwe-silicon carbide. Kodwa-ke, ngesikhathi sokushisa, isihlabathi se-cushion sizofafazwa emotweni yomlilo, futhi indlela yomlilo enengqondo izobekelwa ukuze ukudubula kulingane ngokulinganayo.

Ukudubula kwezitini ezibunjwe nge-silicon kudubula endaweni enciphayo, futhi izinga lokushisa lokudubula liyahlukahluka ngokwezinga elithile emabangeni ahlukene, ngokuvamile phakathi kuka-1428 no-1450°C. Uma isihlabathi sephedi sinamathela endaweni yezitini ngemva kokuphuma kuhko, isihlabathi sephedi singapholishwa bese sifakwa endaweni yokugcina.

Ngamafuphi, ikhwalithi yezitini ezibunjwe nge-silica kanye nezitini ezibomvu ezibunjwe nge-silica zihlukile, futhi ubukhulu be-lining lining esetshenzisiwe buhlukile.
