Nickel Silicide, Ni2Si

Silicon (NiSi) ndeye austenitic (NiSi) chiwanikwa (1); iyo inoshandiswa seyakaipa pole zvinhu zve n-mhando thermocouple. Kugadzikana kwayo kwethermoelectric kuri nani pane iyo yeE, J uye K. mhando yemagetsi vaviri. Munguva pfupi yapfuura, yakanyorwa senge rudzi rweiyo thermocouple mune yakajairwa muyero.

Silicon (NiSi) ndeye austenitic (NiSi) chiwanikwa (1); iyo inoshandiswa seyakaipa pole zvinhu zve n-mhando thermocouple. Kugadzikana kwayo kwethermoelectric kuri nani pane iyo yeE, J uye K mhando yemagetsi vaviri.
Nickel silicon alloy haifanire kuiswa mune gasi ine sarufa. Munguva pfupi yapfuura, yakanyorwa senge rudzi rweiyo thermocouple mune yepasi rose standard.
Ma parameter eNiSi anotevera:
Kemikari kuumbwa: Si: 4.3%, Mg: 0.1%, iyo yakasara iri Ni
Kuwandisa: 8.585g / cm3
Kuramba: 0.365 Ω mm2 / MResistance tembiricha inokwana (20-100 ° C) 689x10 kubvisa simba rechitanhatu / K Koefficient yekuwedzera kwekushisa (20-100 ° C) 17x10 kubvisa simba rechitanhatu / KThermal kuitisa (100 ° C) 27xwm isina simba rekutanga simba K yakaipa simba rekutanga Nzvimbo yekunyungudika: 1420 ° C

Kushanda minda:
Silicon ndiyo inonyanya kushandiswa semiconductor zvinhu. Mhando dzakasiyana dzesimbi yesilide yakadzidzwa yekutaurirana uye yekubatanidza tekinoroji yesemiconductor michina MoSi2, WSI uye
Ni2Si yakaunzwa mukugadzirwa kweyemagetsi michina. Aya mafirita-akavakirwa matete mafirimu ane akanaka anoenderana nesilicon zvinhu, uye anogona kushandiswa kuputira, kuzviparadzanisa, passivation uye kubatana mune yesilicon zvishandiso, NiSi, seyakavimbika kwazvo inozvisarudzira yakasarudzika silicide zvinhu zvemanoscale zvishandiso, yakave yakadzidzwa zvakanyanya kune yayo yakaderera silicon kurasikirwa uye yakaderera kugadzirwa kupisa bhajeti, yakaderera resistivity uye isina linewidth mhedzisiro Mu graphene electrode, nickel silicide inogona kunonoka kuitika kwepurverization uye kutsemuka kwesilicon electrode, uye kugadzirisa kugadzirisa kweye electrode. Iyo yekunyorovera uye yekuparadzira mhedzisiro yenisi2 alloy pane SiC ceramics pakasiyana tembiricha nemuchadenga zvakaongororwa.
