Ren tenndioxid framställs genom att cassiterit [[reduceras]] med [[kol]] i en [[masugn]] vid 1200&amp;nbsp;–&amp;nbsp;1300&amp;nbsp;°C vilket ger metalliskt tenn som sedan förbränns i luft för att ge ren tenndioxid.<br /> <br /> ==Användning==<br /> Tillsammans med [[vanadindioxid]] används tenndioxid som [[katalysator]] vid tillverkning av [[karboxylsyror]]. Tenndioxid används också inom [[keramik]] för att göra [[glasyr (keram)|glasyr]] ogenomskinlig.<br /> <br /> ==Se även==<br /> *[[Tennoxid]]<br /> *[[Kiseldioxid]]<br /> *[[Titandioxid]]<br /> <br /> ==Källor==<br /> *[http://www.jtbaker.com/msds/englishhtml/s6410.htm Material Safety Data Sheet] Mallinckrodt Baker<br /> <br /> {{enwp|url=http://en.wikipedia.org/w/index.php?title=Tin_dioxide&amp;oldid=328870895|artikel=Tin dioxide}}<br /> <br /> [[Kategori:Tennföreningar]]<br /> [[Kategori:Oxider]]<br /> <br /> [[cs:Oxid cíničitý]]<br /> [[de:Zinn(IV)-oxid]]<br /> [[en:Tin dioxide]]<br /> [[es:Dióxido de estaño]]<br /> [[fa:دی‌اکسید قلع]]<br /> [[fr:Dioxyde d&#039;étain]]<br /> [[ko:산화 주석]]<br /> [[it:Diossido di stagno]]<br /> [[hu:Ón-dioxid]]<br /> [[nl:Tin(IV)oxide]]<br /> [[pt:Dióxido de estanho]]<br /> [[ru:Оксид олова(IV)]]<br /> [[simple:Tin(IV) oxide]]<br /> [[sr:Kalaj dioksid]]<br /> [[vi:Thiếc điôxít]]<br /> [[zh:二氧化锡]]</div> Dan Olsson
