How is Germanium Selenide (CAS: 12065-10-0) typically synthesized?

Germanium selenide is commonly synthesized by the reaction of germanium oxide with elemental selenium, or by the reduction of germanium selenate with a reducing agent. Common methods include solid-state reactions, molten salt synthesis, and chemical vapor deposition (CVD). Synthesis typically requires high temperatures and inert atmospheres. Precise control of reaction conditions is necessary to achieve the desired purity and particle size.
