Silicon-barium yog ib qho alloy muaj li ntawmsilicon (si)thiabbarium (ba)Qhov ntawd yog siv rau deoxidation, desulfurization, thiab kev sib piv hauv cov hlau thiab hlau smelting. Mas siv rau deoxidation, desulfurization, thiab alloying hauv steelmaking:
1. Tshuaj lom neeg sib xyaw
Lub ntsiab Cheebtsamyog silicon (si) thiab barium (ba), feem ntau yog tusBA cov ntsiab lus yog 30% rau 60%,Cov ntsiab lus sii yog 40% txog 70%.
Hom Khoom:
Basi30 (nrog BA ~ 30%)
Basi50 (BA ~ 50%)
Basi60 (BA ~ 60%)
Kev tsis loj: Tej zaum yuav muaj me me ntawm txhuas (al), calcium (Ca), carbon (c), phosphorus (p), leej faj (s) thiab lwm yam.
2. Lub zog lub cev
Cov khoom tseem ceeb / Cov Cwj Pwm
Kev tshwm simSilvery-grey lossis tsaus grey lumps / granules
Ceev3.5 ~ 4.5g /M³ (nyob ntawm BA cov ntsiab lus)
Melting point1100 ~ 1300 DEGLECE (Melting taw tes ntawm Silicon-Barium Alloy yog qis dua li ntawm cov ntshiab barium)
Kev nyuajNkig, yooj yim rau
kev soKev coj uaCov khoom lag luam semiconductor (nyhuv ntawm silicon)
3. Tshuaj lom neeg
Siab dua:
Chines (BA) yog lub ntiaj teb muaj zog alkaline hlau, thiab sillicon (si)
Cov tshuaj tiv thaiv nrog oxygen:
BA + O2 → BoA (nrawm dua) Si + O2 → Sio2
Cov tshuaj tiv thaiv nrog cov leej faj (desulfurization):
BA + S → Bas
Corrosion Kuj:
Nws yog ruaj khov nyob rau hauv cov huab cua qhuav, tab sis yooj yim oxidizes nyob rau hauv huab cua noo.
Reacts ua txhaum nrog dej los yog acid, tso hydrogen (h₂):
Ba {{{{}} h2o → ba (huag) 2+ h2}
