Gallium (I) oxide is an inorganic chemical compound of gallium from the group of oxides .

Extraction and presentation

Gallium (I) oxide can be obtained by reacting gallium (III) oxide in a vacuum with heated gallium.

{\ displaystyle \ mathrm {Ga_ {2} O_ {3} +4 \ Ga \ longrightarrow 3 \ Ga_ {2} O}}

It can also be obtained by reacting gallium with carbon dioxide at low pressure and 850 ° C.

{\ displaystyle \ mathrm {2 \ Ga + CO_ {2} \ longrightarrow Ga_ {2} O + CO}}

It is also produced in the manufacture of gallium arsenide wafers through reaction with silicon dioxide from quartz substrates .

{\ displaystyle \ mathrm {4 \ Ga + SiO_ {2} \ longrightarrow 2 \ Ga_ {2} O + Si}}

properties

Gallium (I) oxide is a brown-black diamagnetic solid that is resistant to dry air. Noticeable volatilization takes place at 660 ° C. in an inert gas stream of 1 bar. In a high vacuum, volatilization occurs from 500 ° C and from 700 ° C decomposes into gallium (III) oxide and gallium.
