'''Bariumoxid''' är en [[oxid]] av [[barium]] med [[kemisk formel|formeln]] BaO.<br />
<br />
==Egenskaper==<br />
Bariumoxid reagerar med vatten och bildar [[bariumhydroxid]] (Ba(OH)<sub>2</sub>).<br />
:<math>\rm BaO + H_2O \rightarrow Ba(OH)_2</math><br />
<br />
==Framställning==<br />
Bariumoxid kan framställas genom [[kalcinering]] av [[bariumkarbonat]] (BaCO<sub>3</sub>), [[bariumhydroxid]] (Ba(OH)<sub>2</sub>) eller [[bariumnitrat]] (Ba(NO<sub>3</sub>)<sub>2</sub>).<br />
:<math>\rm BaCO_3\ \xrightarrow{\Delta}\ BaO + CO_2</math><br />
<br />
:<math>\rm Ba(OH)_2\ \xrightarrow{\Delta}\ BaO + H_2O</math><br />
<br />
:<math>\rm 2\ Ba(NO_3)_2\ \xrightarrow{\Delta}\ 2\ BaO + 2\ NO_2 + O_2</math><br />
<br />
==Användning==<br />
*Bariumoxid används för att skydda ytan på den varma [[katod]]en i [[katodstrålerör]].<br />
*Det har också ersatt [[blyoxid|bly(II)oxid]] vid tillverkning av [[kronglas]]. Bariumoxid är inte lika [[gift]]igt och har lägre [[dispersion]].<br />
<br />
==Se även==<br />
*[[Bariumperoxid]]<br />
*[[Kalciumoxid]]<br />
