Gallium metal

Manufactured by Merck Group
Sourced in United States

Gallium metal is a soft, silvery-white metallic element with the atomic number 31. It has a low melting point and is solid at room temperature. Gallium metal is primarily used in the production of semiconductor devices, such as integrated circuits and light-emitting diodes (LEDs), as well as in the manufacture of certain types of thermometers.

All the chemicals and reagents i.e., Gallium metal, ethylene diamine, sodium sulphate (Na2SO4), ethanol and acetone were purchased from Sigma Aldrich and used as received unless otherwise stated. For synthesis, few grams of Gallium metal are mixed with ethylenediamine and placed in an ultrasonic bath for an hour at 75 °C. During the ultrasonification, deionized water is added in 5 ml portions after every 5 min. time span. The appearance of black suspension showed the formation of Ga- ethylenediamine complex. After complete dissolution of Gallium metal in ethylenediamine water solution, the reaction mixture is shifted into a stainless steel autoclave containing a Teflon vessel. The solvothermal reaction is carried out for 3, 6, 12 and 24 hours at 180 °C respectively. Afterwards the reaction mixture containing precipitates of Galliumoxynitride (GaON) in each case is centrifuged at 4000 RPM for 5 mins washed with ethanol and acetone respectively before drying in a vacuum oven at 100 °C for two hours. Furthermore, the as prepared GaON nanosheets at 180 °C for 24 hours is further annealed at 500 °C for 4 hours owing to its best morphology achieved for comparative PEC studies.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
