Nā waiwai a me ka palekana o ka metala silika

He kila hina hina keleka kala, ʻeleʻele ke silikona amorphous. ʻAʻole ʻona, ʻono ʻole. D2.33; Ka helu hehee 1410 ℃; 'Awelika wela wela (16 ~ 100 ℃) 0.1774cal /(g - ℃). ʻO ke kilikakika Crystalline he aniani atomika, paʻakikī a ʻālohilohi, a he ʻano maʻamau o nā semiconductors. Ma ka lumi wela, ma waho aʻe o ka hydrogen fluoride, paʻakikī ke hana me nā mea ʻē aʻe, ʻaʻole hiki ke hoʻoheheʻe ʻia i ka wai, ka waikawa nitric a me ka waikawa hydrochloric, hiki ke hoʻoheheʻe ʻia i ka waika hydrofluoric a me ka lye. Hiki iā ia ke hui pū me ka oxygen a me nā mea ʻē aʻe i nā wela kiʻekiʻe. Loaʻa iā ia nā hiʻohiʻona o ka paʻakikī kiʻekiʻe, ʻaʻohe wai absorption, pale wela, pale ʻana i ka waikawa, kūpaʻa ʻaʻahu a me ke kūpaʻa ʻelemakule. Hoʻolaha nui ʻia ʻo Silicon ma ke ʻano a loaʻa ma kahi o 27.6% i loko o ka ʻōpala o ka Honua. ʻO ka mea nui ma ke ʻano o ka silica a me nā silicates.

ʻO ka metala silika ponoʻī ʻaʻole ia he mea ʻawaʻawa i ke kino o ke kanaka, akā i ke kaʻina hana e hoʻopuka i ka lepo silika maikaʻi, he hopena hoʻoulu i ka ʻōpū hanu. E hoʻohana i nā mea pale kūpono e like me nā maka, nā mīkina lima, a me ka pale maka i ka wā e lawelawe ana i ka metala silika.

LDso waha o nā ʻiole: 3160mg/kg. ʻO ka inhalation noʻonoʻo kiʻekiʻe ke kumu o ka huhū haʻahaʻa o ka ʻōpū hanu a me nā mea hoʻonāukiuki ke komo i ka maka ma ke ʻano he kino ʻē. Hoʻopili ikaika ka pauka silika me ka calcium, cesium carbide, chlorine, diamond fluoride, fluorine, iodine trifluoride, manganese trifluoride, rubidium carbide, silver fluoride, potassium sodium alloy. He pōʻino ka lepo ke ʻike ʻia i ka lapalapa a i ʻole ke hoʻopili ʻana me nā mea ʻokiʻoki. E kūʻai i loko o kahi hale kūʻai maloʻo, maloʻo a maikaʻi. E mālama i ke ahi a me ka wela. Pono e hoʻopaʻa ʻia ka pūʻolo a ʻaʻole pili i ka ea. Pono e hoʻokaʻawale ʻia mai nā oxidizer, a mai hui pū.

Eia kekahi, e hoʻopili ka metala silika me ka oxygen i ka lewa e hana i ke kinoea lapalapa, a pono e uku ʻia e pale aku i ka hoʻopili ʻana me nā kumu ahi a i ʻole nā ​​​​mea ʻona i ka wā o ka mālama ʻana a me ka lawe ʻana.
