Germanium Telluride powder is a black or dark gray powder with the chemical formula GeTe₂. It has specific physicochemical properties and has important applications in electronics, phase change storage, thermoelectric materials, and infrared detection.

Properties

Chemical formula: GeTe₂.

Molecular weight: about 343.96

Appearance: Usually black or dark gray powder, uniform color, no obvious impurities. Its color is mainly determined by its internal electronic structure and the nature of chemical bonding, the absorption and reflection of light show a specific pattern, making it show this dark appearance.

Density: The theoretical density is approximately 7.32 g/cm³, but the actual density may vary slightly depending on the particle size of the powder, the method of preparation, and other factors. The magnitude of the density affects its physical behavior during storage, transportation, and mixing with other materials.

Stability: Under normal temperature and pressure, Germanium Telluride powder has certain chemical stability, but under conditions of high temperature, humidity or strong oxidation, its chemical activity will be enhanced and chemical reactions will occur easily. For example, when heated in air, it may undergo an oxidizing reaction with oxygen, leading to changes in its composition and properties.

Oxidizing and Reducing Properties: Germanium and tellurium elements in Germanium Telluride have certain oxidizing and reducing properties, which makes the powder able to participate in a variety of redox reactions. It can react with a number of metals, non-metals or compounds to produce the corresponding germanium compounds, tellurium compounds or other complex compounds, a property that provides the basis for its application in materials synthesis and chemical reactions.

Reaction with acids and bases: Germanium Telluride powder can react with strong acids and bases to produce corresponding salts and other compounds. Therefore, it is necessary to avoid contact with acids, bases and other corrosive substances during handling and use to prevent dangerous reactions, and this also provides a reaction pathway for its use in certain specific chemical processes.
