Dab tsi yog tus nqi ntawm calcium silicon hnub no? Dab tsi yog kev siv cov calcium silicon?

Calcium silicon (Casi) yog ib qho tseem ceeb ntawm cov hlau thiab lub zog. Nws ua raws li tus deoxidization muaj zog (rov qab siv cov pa oxygen zoo li cao thiab sio₂, txo cov txiv duaj porosity) thiab desulfurizer (khi kev ua haujlwm, txhim kho ductility). Nws kuj tseem ua kom zoo dua qoob loo qauv, txhim kho kev ua kom nruj, nkees ua hauj lwm, thiab kev ua kom muaj cov hlau.

Silicon calcium (los yog "calcium silicon") yog binary li feem ntau muaj ntawm silicon (~ 45%) thiab calcium (~ 55-65%), nrog kab hlau. Cov lus cog tseg yog hloov tau yooj yim - nws ua haujlwm zoo rau cov calcium silicon, ua hauj lwm zoo dua rau kev ua kom zoo nkauj hlau / cam khwb cia hlau ua kom zoo nkauj thiab kev ua tau zoo.

Calcium silicate (suav nrog ntuj wollastonite, Casio₃) muaj dav siv:

​Kev rwb thaiv tsev: Tsawg thermal conductivity ua nws zoo tagnrho rau kev ua tsev / muaj cov cua sov thermal.

​Ntawv refactories: High Melting taw tes (~ 1540 degree) suits rauv lub lauj kaub linings / cib.

​Cov fillers: Txhim kho lub zog / durability nyob rau hauv plastics, roj hmab, thiab xim pleev xim.

​Maas / Ceramics: Txhim kho lub hardness / tshuaj ruaj khov nyob rau hauv Portland Maas thiab glazes.

​Kev ua teb: Qee zaum siv ua calcium / silicon av txias.

Casio₃ yog kab xevCalcium silicateCov. Nws cov ntawv ntxhia tshaj plaws yogWollastoniteCov. Muaj cov ntsiab lus muaj kuj tseem tuaj yeem xa mus rau nws yog "txheem calcium" (tus qauv tsawg dua), tab sis "calcium silicate" tseem yog lub npe tseem ceeb.
