'''Divätetellurid''' är en kemisk förening mellan [[väte]] och [[tellur]]. Vid [[standardtryck och -temperatur]] är det en [[gas]] som är mycket [[giftig]]. Divätetellurid kan börja brinna ganska lätt vid tillgång av [[syrgas]] och bildar då [[tellurdioxid]] och [[vatten]].<br />
<br />
==Egenskaper==<br />
Divätetellurid är reagerar med [[syre]]t i [[luft]] och sönderfaller till vatten och [[tellur]].<br />
:<math>\rm 2\ H_2Te + O2 \rightarrow 2\ H_2O + 2\ Te</math><br />
<br />
==Produktion==<br />
Divätetellurid kan produceras genom att låta salter som [[aluminiumtellurid]] (Al<sub>2</sub>Te<sub>3</sub>) eller [[natriumtellurid]] (Na<sub>2</sub>Te) reagera med vatten eller genom rekation mellan tellur och vätgas vid höga temperaturer.<br />
:<math>\rm H_2 + Te \rightarrow H_2Te</math><br />
