01 /Applications

Synthesis of Ternary Silicides

Gallium's broad liquid range has been leveraged as a solvent for synthesising ternary silicides like SmNiSi₃ and YNiSi₃. This novel synthetic method allows for the creation of these compounds without incorporating gallium into their final structure.

Materials Science

As a metal with unique thermal and electrical properties, gallium finds application in various materials science research and development areas. Its low melting point and density are key characteristics exploited in advanced material formulations.

Specialised Reagents

Gallium serves as a specialised reagent in certain chemical synthesis pathways. Its distinct chemical behaviour allows for specific reactions and the formation of unique inorganic compounds.
