Silicon Dioxide | 7631-86-9

Ginin sinadari Silicon Dioxide, kuma aka sani da silica (daga silex na Latin), oxide ne na silicon tare da dabarar sinadarai SiO2. An san ta da taurinta tun zamanin da. An fi samun siliki a cikin yanayi kamar yashi ko ma'adini, da kuma a cikin bangon tantanin halitta na diatoms.
Ana ƙera silica ta nau'i-nau'i da yawa ciki har da ma'adini da aka haɗa, crystal, silica fumed (ko pyrogenic silica), colloidal silica, silica gel, da aerogel.
Ana amfani da siliki da farko wajen samar da gilashin tagogi, gilashin sha, kwalabe na abin sha, da sauran abubuwan amfani. Yawancin filaye na gani don sadarwa kuma an yi su daga silica. Abu ne na farko na kayan farar fata da yawa kamar kayan yumbu, kayan dutse, alin, da siminti na Portland na masana'antu.
Silica ƙari ne na kowa a cikin samar da abinci, inda ake amfani da shi da farko azaman wakili mai gudana a cikin abinci mai foda, ko don sha ruwa a aikace-aikacen hygroscopic. Shi ne babban bangaren diatomaceous ƙasa wanda ke da amfani da yawa tun daga tacewa zuwa sarrafa kwari. Har ila yau, shi ne kashi na farko na tokar shinkafar da ake amfani da ita, misali, wajen tacewa da kera siminti.
Fina-finan silica na siliki da aka girma akan wafers ta hanyar hanyoyin iskar oxygen ta thermal na iya zama da amfani sosai a cikin microelectronics, inda suke aiki azaman insulators na lantarki tare da kwanciyar hankali na sinadarai. A cikin aikace-aikacen lantarki, yana iya kare silicon, cajin ajiya, toshe halin yanzu, har ma yana aiki azaman hanyar sarrafawa don iyakance kwararar yanzu.
An yi amfani da jirgin sama mai tushen silica a cikin kumbon na Stardust don tattara ɓangarorin da suka wuce ƙasa. Ana kuma amfani da Silica wajen fitar da DNA da RNA saboda ikonta na ɗaure ga ƙwayoyin nucleic a ƙarƙashin kasancewar chaotropes. A matsayin silica hydrophobic ana amfani dashi azaman ɓangaren defoamer. A cikin nau'i mai ruwa, ana amfani da shi a cikin man goge baki a matsayin mai wuyar gogewa don cire plaque na hakori.
A cikin iyawarsa a matsayin refractory, yana da amfani a cikin nau'in fiber a matsayin masana'anta na zafin jiki mai zafi. A cikin kayan shafawa, yana da amfani don abubuwan da ke yaɗa haske da kuma ɗaukar yanayi. Ana amfani da silica na colloidal azaman ruwan inabi da kuma ruwan 'ya'yan itace. A cikin samfuran magunguna, silica yana taimakawa foda yayin da aka kafa allunan. Hakanan ana amfani dashi azaman fili na haɓaka yanayin zafi a masana'antar famfo mai zafi na ƙasa.
