ʻO ka Silicon dioxide, i ʻike nui ʻia ʻo silica, e pili ana i nā ʻano like ʻole e like me ka silica fumed, silica precipitated, a me ka silica colloidal, kēlā me kēia me nā waiwai kū hoʻokahi i hana ʻia no nā noi ʻoihana. ʻO kēia hui inorganic, i haku ʻia me ka silicon a me ka oxygen, ua mahalo ʻia no kona maʻemaʻe kiʻekiʻe, kūpaʻa wela, a me nā ʻano kino like ʻole e like me ka ʻili nui a me ka nui o nā ʻāpana liʻiliʻi.

ʻO ka silica i hoʻoheheʻe ʻia, i hana ʻia ma o nā hopena kemika i loko o nā hopena wai, loaʻa nā noi ma ka ʻāpana kāmaʻa, e hoʻohui ana i ka maʻalahi a me ka cushioning i nā kapuaʻi kāmaʻa. ʻO kona hiki ke omo kiʻekiʻe e lilo ia i mea nui i nā pena a me nā uhi, kahi e hana ai ma ke ʻano he mea mānoanoa, e pale ana i ka sagging a hoʻomaikaʻi i ke kaohi kahe. I loko o nā mea hoʻopili a me nā sealant, hoʻonui ia i ka viscosity a me ka ikaika hoʻopaʻa, e hōʻoiaʻiʻo ana i ka hana hilinaʻi ma nā ʻano kaiapuni like ʻole.

Ma ka ʻāpana hoʻonani a me ka mālama pilikino, hana ka silica ma ke ʻano he mea hoʻomoʻa i nā huahana e like me nā pauka maka a me nā deodorants, e kōkua ana i ka kaohi ʻana i ka ʻaila a me ka makū me ka ʻole o ka hoʻonāukiuki ʻana i ka ʻili. ʻO kona ʻano inert e hōʻoiaʻiʻo i ka launa pū ʻana me nā mea ʻē aʻe, e lilo ia i mea hoʻohui palekana a maikaʻi hoʻi.

ʻO ke kūpaʻa ʻana o ka Silicon dioxide i nā mahana kiʻekiʻe a me ka palaho kemika e hoʻonui hou aku i kona hoʻohana ʻana i nā mea refractory, kahi e hāʻawi ai i ke kūpaʻa o nā uhi umu a me ka insulation wela kiʻekiʻe. ʻO kona nui ma ke ʻano a me ka hiki ke hana ʻia e kūlike me nā koi ʻoihana hou no nā mea e pili ana i ke kaiapuni, e hoʻopaʻa ana i kāna kuleana ma ke ʻano he ʻāpana kumu ma nā ʻāpana hana like ʻole.
