Hoʻohana nui ʻia ka metala silika, ʻike ʻia ʻo crystalline silicon a i ʻole silika ʻenehana, ma ke ʻano he additive no ka alloy non-ferrous. Hoʻopili ʻia ʻo Silicon Metal e ka silika ʻoihana maikaʻi loa a me nā ʻano like ʻole. Hoʻohana ʻia i ka electro, metallurgy a me ka ʻoihana kemika. ʻO ke kala hina a i ʻole ʻeleʻele ʻeleʻele me ka ʻulaʻula metala, ʻo ia ka helu heheʻe kiʻekiʻe, ke kūpaʻa wela maikaʻi, ka resistivity kiʻekiʻe a me ke kūpaʻa oxidation kiʻekiʻe. He ʻelua alotrope ka silikoni: silikona amorphous a me ke silikona crystalline.
Noi:
Hoʻohana nui ʻia ʻo 1.Silicon i ka hoʻoheheʻe ʻana i nā mea hoʻoheheʻe ʻia, ma ke ʻano he mea hoʻohaʻahaʻa i nā ʻano mea he nui.
2.Silicon metala Hoʻohana nui ʻia i ka refractory mea a me ka mana metallurgy ʻoihana e hoʻomaikaʻi i ka pale ʻana i ka wela, ʻaʻahu i ke kūpaʻa a me ke kūpaʻa oxidation.
3.Industrial silicon pauka i manaoia e like me ka mea hoʻohui hui, hoʻomaikaʻi i ke kila hardenability i ka metallurgy a me ka foundry oihana.
4. Hoʻohana nui ʻia ia i ka hana ʻana i nā ʻāpana, polycrystalline silicon, nā mea silika organik a me ka refractor kiʻekiʻe.

FAQ
Nīnau: He hale hana ʻoe a he hui kālepa paha?
A: He hale hana mākou a me ka hui kālepa.
Q: Hiki iaʻu ke loaʻa kaʻu LOGO ponoʻī ma ka huahana?
A: ʻAe, hiki iā ʻoe ke hoʻouna mai iā mākou i kāu hoʻolālā a hiki iā mākou ke hana i kāu LOGO.
Q: Hiki iā ʻoe ke hoʻonohonoho i ka hoʻouna?
A: ʻOiaʻiʻo, loaʻa iā mākou ka mea lawe ukana mau loa e hiki ke loaʻa ke kumukūʻai maikaʻi loa mai ka hapa nui o nā hui moku a hāʻawi i ka lawelawe ʻoihana.
Q: Hiki iā mākou ke kipa i kāu hale hana?
A: Hoʻokipa maikaʻi ʻia inā loaʻa iā mākou kāu papa hana e kiʻi mākou iā ʻoe.
