Differential thermal analysis of germanium (II) sulfide was investigated. Melting point of GeS is 665oC. GeS nanoparticles may be prepared by gas phase laser photolysis, to be used in lithium ion batteries. GeS films may be generated by electrochemical deposition and used as an electrolyte. A study also reports the formation of GeS clusters by laser ablation. | [reaction suitability]

| Questions And Answer | Back Directory | [Application]
Germanium sulfide is a substance that highly absorbs microwave radiation. Therefore, when sulfidation is carried out using microwave radiation, only the sulfides selectively absorb microwave radiation, generating instantaneous high temperatures. This causes germanium to react with sulfur to form germanium sulfide, which continues to absorb microwave radiation until it reaches the temperature for sublimation and volatilization. Microwave radiation has strong and uniform penetrability, resulting in high volatilization efficiency of germanium sulfide without generating excessively high local temperatures. The product obtained is mainly germanium sulfide, which is beneficial for subsequent processing. Compared to fuming furnaces, rotary kilns have superior indirect heating methods and heat conduction through a medium. |
