Magnesium telluride is a binary inorganic compound of magnesium and tellurium with the formula MgTe, colorless (white) crystals, reacts with water.

Content

Getting

Heating stoichiometric amounts of pure substances in a stream of hydrogen :

{\mathsf {Mg+Te\ {\xrightarrow {T}}\ MgTe}}

{\ displaystyle {\ mathsf {Mg + Te \ {\ xrightarrow {T}} \ MgTe}}}

Physical Properties

Magnesium telluride forms colorless (white) crystals of hexagonal syngony , space group P 6 ₃ mc , cell parameters a = 0.453 nm, c = 0.738 nm, Z = 2.

Chemical Properties

Reacts with moisture from the air:

{\mathsf {MgTe+2H_{2}O\ {\xrightarrow {}}\ Mg(OH)_{2}+H_{2}Te}}

{\ displaystyle {\ mathsf {MgTe + 2H_ {2} O \ {\ xrightarrow {}} \ Mg (OH) _ {2} + H_ {2} Te}}}

the resulting tellurium is oxidized, forming a deposit of black tellurium:

{\mathsf {2H_{2}Te+O_{2}\ {\xrightarrow {}}\ 2Te+H_{2}O}}

{\ displaystyle {\ mathsf {2H_ {2} Te + O_ {2} \ {\ xrightarrow {}} \ 2Te + H_ {2} O}}}
