Metala Silika
Gnā hiʻohiʻona nui o ka metala silika
Ua ʻike ʻia ka metala silika he silikoni metallurgical a i ʻole, ʻoi loa, e like me ke silika.ʻO Silicon ponoʻī ʻo ia ka ʻewalu o nā mea nui loa i ke ao holoʻokoʻa, akā ʻike ʻole ʻia ma ke ʻano maʻemaʻe ma ka Honua.Ua hāʻawi ka US Chemical Abstracts Service (CAS) i ka helu CAS 7440-21-3.ʻO ka metala silikoni ma kona ʻano maʻemaʻe, he ʻeleʻele hina, ʻulaʻula, metalloidal me ka ʻala ʻole.He kiʻekiʻe loa kona helu heheʻe a me ka paila.Hoʻomaka ka hoʻoheheʻe ʻana o ke kilika metala ma kahi o 1,410°C.ʻOi aku ka kiʻekiʻe o ka paila a hiki i ka 2,355°C.He haʻahaʻa loa ka hoʻoheheʻe wai o ka metala silika i manaʻo ʻia ʻaʻole hiki ke hoʻoheheʻe ʻia i ka hana.

Ka nui o ka ʻāpana: 10〜120/150mm, hiki ke hana maʻamau e nā koi;
Pākē: Hoʻopili ʻia i nā ʻeke ukana maʻalahi 1-Ton, hāʻawi pū i ka pūʻolo e like me nā koi o nā mea kūʻai aku;
He aha ka Silicon Metal i hoʻohana ʻia no?
Hoʻohana pinepine ʻia ʻo Silicon Metal e like me ka hana ʻana i ka ʻoihana kemika no ka hana ʻana i nā siloxanes a me nā silicones.Hiki ke hoʻohana ʻia ka metala silika ma ke ʻano he mea koʻikoʻi i ka uila a me nā ʻoihana solar (silicon chips, semi-conductors, solar panels).Hiki iā ia ke hoʻomaikaʻi i nā waiwai pono o ka alumini e like me ka castability, paʻakikī a me ka ikaika.ʻO ka hoʻohui ʻana i ka metala silika i nā alumini alumini e māmā a ikaika.No laila, hoʻohana nui ʻia lākou i ka ʻoihana automotive.Hoʻohana ʻia e pani i nā ʻāpana hao ʻoi aku ke kaumaha.ʻO nā ʻāpana kaʻa e like me nā poloka ʻenekini a me nā kaʻa kaʻa ka mea maʻamau i hoʻolei ʻia i nā ʻāpana silika alumini.
Hiki ke hoʻohālikelike ʻia ka noi ʻana o Silicon Metal e like me lalo:
● alumini alumini (e laʻa me nā alumini alumini ikaika kiʻekiʻe no ka ʻoihana kaʻa).
● hana i nā siloxanes a me nā silicones.
● mea hoʻokomo mua i ka hana ʻana i nā modula photovoltaic.
● ka hana ʻana o ka silikoni papa uila.
● hana o ka synthetic amorphous silica.
● nā noi ʻoihana ʻē aʻe.
