Natriumnitraatti (CAS 7631-99-4)<\/strong> <\/p>\n

Natriumnitraatti (NaNO3) on valkoinen kiinte\u00e4 suola, joka liukenee hyvin veteen. Natriumnitraattia kutsutaan my\u00f6s nimill\u00e4 chilen- ja perunsalpietari erotuksena perinteisest\u00e4 salpietarista, joka on kaliumnitraattia.<\/p>\n

Natriumnitraattia k\u00e4ytet\u00e4\u00e4n lannoitteisiin, pyrotekniikassa, s\u00e4il\u00f6nt\u00e4aineena, rakettien polttoaineessa, nitrauskemikaalina, hapettimena sek\u00e4 lasin ja keramiikan valmistuksessa.<\/p>\n

Chilen, Perun ja Bolivian v\u00e4linen Tyynenmeren sota sai osittain alkunsa taistelusta alueen rikkaista natriumnitraattivaroista. Maailman suurimmat salpietarimalmiesiintym\u00e4t oli Atacaman aavikolla. Natriumnitraattia kaivettiin alueella runsaasti 1940-luvulle saakka. Natriumnitraatin arvo oli laskenut koko 1900-luvun, mihin vaikutti Haber-Bosch-menetelm\u00e4n kehitt\u00e4minen.<\/p>\n

Salpietarimalmia kaivetaan Chilest\u00e4 edelleen. Siit\u00e4 saadaan natriumnitraatin lis\u00e4ksi kaliumnitraattia, natriumsulfaattia ja jodia. Natriumnitraattia valmistetaan my\u00f6s keinotekoisesti neutralisoimalla typpihappoa soodalla.<\/p>\n
