Cov Lus Qhia Tshwj Xeeb Ntawm Cov Hlau Silicon Hmoov
Tshuaj lom neeg muaj feem (cov qib kev coj dawb huv)
Lub purity ntawm silicon hmoov yog qhov tseem ceeb rau nws daim ntawv thov. Cov qib kawm muaj xws li:
| Teem nqi | SI cov ntsiab lus (%) | Lub ntsiab impurities (max%) | Cov Kev Siv Raug Raug |
|---|---|---|---|
| Metallurgical Qib | 98.0–99.0% | Fe ({{{{{0}}}. 5%), al ({}. 5%), ca (0.3%) | Alloys, recractories, deoxidizers |
| Tshuaj Khib Qib | 99.0–99.5% | Fe ({{{{{{0}}}. 4%), al ({}. 4%), ca (0.2%) | Silicones, silices, ceramics |
| Qib hluav taws xob | Ntau dua los yog sib npaug rau 99.999% (6n) | B, P, C, O (PPM qib) | Semiconductor Wafers, Solar hlwb |
Qhov loj me me faib
Qhov loj me cuam tshuam rau kev cuam tshuam, sintering tus cwj pwm, thiab flowability. Cov Kev Kawm Tib Neeg:
| Ntaus | Particle loj li cas | Txuj Ci Ntau Lawm | Cov Ntawv Thov |
|---|---|---|---|
| Coarse hmoov | 100–500 µm | NEEG KHO TSHUAB SIB TSOO | Metallurgy, Readvactories |
| Hmoov hmoov | 10–100 µm | Dav hlau milling, pob milling | Tshuaj Lom Tshuaj Synthesis, 3D Luam Ntawv |
| Ultrafine Hmoov | 1–10 µm | Tshuaj Vauv Vacor Deposition (CVD) | Roj teeb, tsho nplaum |
| NANO Hmoov | <1 µm (nanoscale) | Ntshav synthesis | Cov khoom siv hluav taws xob, kev sib tw advanced |
Morphology & Cov Khoom Siv Lub Cev
Cov duab:Tsis xwm yeem (crushed), kheej kheej (atomized), lossis ntxeem tau (rau thaj chaw siab).
Bulk ntom:{{0 {0}}. 5-1.5 g \/ cm³ (sib txawv nrog particle loj thiab cov duab).
Thaj Chaw:1-50 m² \/ g (ntsuas los ntawm kev twv txoj cai; siab dua rau nano hmoov).
Cov Qauv Tseem Ceeb
Ntau yam kev lag luam ua raws cov qauv tshwj xeeb rau Silicon Hmoov:
