Hlau silicon hmoov tsuas yog silicon ingots hauv av rau hauv hmoov. Cov neeg muas zaub uas yuav cov hmoov no feem ntau poob rau hauv ob pawg:

Thawj qeb:Kev siv metallurgical (steel deoxidation, aluminium alloys, casting inoculants). Cov neeg siv khoom no tsis tas yuav muaj purity siab heev (97%-99%), tab sis lawv tshwj xeeb txog qhov loj me-zoo heev thiab nws haus luam yeeb thiab khib nyiab; ntxhib heev thiab nws yuav tsis yaj zoo.

Qib thib ob:Rau kev siv tshuaj (organosilicon monomers, silanes, silica). Cov neeg siv khoom no xav tau ob qho tib si purity siab thiab siab loj (siab dua 99%, siab dua 200 mesh) vim tias impurities yuav lom cov catalyst hauv tshuaj lom neeg.

Muaj qib (purity 97% -99%)

Siv: steel deoxidation, aluminium alloy batching, casting inoculants.

Kev xaiv loj: 50-100 mesh feem ntau siv. Qhov loj me no dissolves sai sai rau hauv ib lub ladle yam tsis haus luam yeeb los yog absorbed zoo li hmoov.

Purity xaiv:97%los yog553txaus; siv441yog khib nyiab. Qhov no yog vim metallurgy feem ntau siv silicon lub deoxidation thiab alloying zog, ua rau nws tsis tshua muaj siab rau impurities.

Chemical qib (purity 99% lossis siab dua)

Daim ntaub ntawv: Organosilicon monomer synthesis (rau silicone roj thiab roj hmab), silane gas, silica.

Kev xaiv loj:200-500 mesh; finer particles ua rau cov tshuaj tiv thaiv sai. Rau fluidized txaj reactors hauv organosilicon ntau lawm,325 meshyog lub ntsiab.

Purity xaiv: 441, 3303, 2202; purity siab dua txo qhov kev pheej hmoo ntawm catalyst lom. Rau siab -kawg organosilicon ntau lawm, txawm tias cov hmoov tshwj xeeb nrog purity tshaj 99.9% yog siv.
