    Metala Silika

    ʻIke mau ʻia ka metala silikon ma ke ʻano he silikona metala a i ʻole ke silikona metala ma muli o kona kala metala ʻālohilohi. I ka ʻoihana, hoʻohana nui ʻia ia ma ke ʻano he alulumi alumina a i ʻole he mea semiconductor. Hoʻohana pū ʻia ka metala silika i ka ʻoihana kemika e hana i nā siloxanes a me nā silicones. Ua manaʻo ʻia ʻo ia he kumu waiwai ma nā wahi he nui o ka honua. Ke hoʻomau nei ka ulu ʻana o ka hoʻokele waiwai a me ka hoʻohana ʻana o ka metala silika ma ka pae honua. Hoʻokō ʻia kahi ʻāpana o ka noi mākeke no kēia mea maka e ka mea hana a me ka mea hāʻawi i ka metala silika - UrbanMines.
