Ihe mgbakwunye ígwè silicon 3303,441,553 maka ihe nkedo alloy aluminum

N'ụlọ ọrụ mmepụta ihe, a na-emepụtakarị silicon ígwè site na ibelata silica na carbon n'ime ọkụ eletrik.

Usoro mmeghachi omume kemịkalụ: SiO2 + 2C→Si + 2CO

Ịdị ọcha nke silikọn e nwetara n'ụzọ a bụ 97~98%, nke a na-akpọ silikọn ígwè. A na-agbaze ya ma megharịa ya ọzọ, a na-ewepụkwa ihe ndị na-adịghị mma na acid iji nweta silikọn ígwè nke dị ọcha nke 99.7~99.8%.

Ihe mejupụtara silicon ígwè bụ silicon, ya mere o nwere ihe ndị yiri silicon.
Silicon nwere allotropes abụọ:silicon amorphous na kristal silicon.

Silicon amorphous bụ ihentụ ntụ ojii isi awọnke ahụ bụ n'ezie microcrystal.

Silicon kristal nwere mmetụta dị nroỌdịdị kristalnaNjirimara semiconductor nke diamond,ebe agbaze bụ 1410°C, ebe esi mmiri bụ 2355°C, ike siri ike nke Moh bụ 7, ọ na-agbawa agbawa. Silicon amorphous na-arụ ọrụ kemịkalụ ma nwee ikena-ere ọkụ nke ukwuu na oxygenỌ na-emeghachi omume na ihe ndị na-abụghị ọla dịka halogen, nitrogen na carbon na okpomọkụ dị elu, ọ nwekwara ike imekọrịta na ọla dịka magnesium, calcium na iron iji mepụta silicide. Silicon amorphous fọrọ nke nta ka ọ ghara ịgbaze na asịd niile na-adịghị agbaze na organic gụnyere hydrofluoric acid, mana ọ na-agbaze na asịd ndị a gwakọtara agwakọta nke nitric acid na hydrofluoric acid. Sodium hydroxide ngwọta nwere ike ịgbaze silicon amorphous ma wepụta hydrogen. Silicon kristal anaghị arụ ọrụ nke ọma, ọ naghị ejikọta ya na oxygen ọbụlagodi na okpomọkụ dị elu, ọ naghị agbaze na asịd inorganic na organic ọ bụla, mana ọ na-agbaze na asịd nitric acid na hydrofluoric acid na sodium hydroxide ngwọta.

A na-eji nnukwu silicon eme ihe maka ịgbaze ferrosilicon alloy dị ka ihe na-agwakọta ígwè na ígwè, nakwa dị ka ihe na-ebelata agbaze ọtụtụ ụdị ígwè. Silicon bụkwa ezigbo ihe dị na aluminum alloy, ọtụtụ aluminum alloy ndị a kpụrụ akpụ nwekwara silicon.
