SnSe powder is an inorganic compound material with unique physical and chemical properties.
Chemical formula and composition: The chemical formula of SnSe indicates that it consists of tin (Sn) and selenium (Se) in a 1:1 atomic ratio.
Molecular weight: 197.67.
Appearance: SnSe powders are generally grey-black or black in colour.
Crystal structure: It has an orthorhombic crystal structure.
Density: The density is approximately 6.14 g/cm³.
Melting point: The melting point is approximately 861°C. Near the melting point, the crystal structure and physical properties of SnSe change significantly.
Thermal conductivity: The low thermal conductivity of SnSe powders is a key advantage for thermoelectric applications.
Thermoelectrics: Based on the low electrical and thermal conductivity and the unique crystal structure of SnSe powders, thermoelectrics can be used to convert heat and electricity in the presence of a temperature difference.
Optoelectronic Devices: Tin Selenide powders have light absorption and light emission properties in the visible and near-infrared regions, which are related to their electronic and crystal structures.
Lithium-ion batteries: Sn and Se elements in SnSe powders react with lithium ions in a reversible manner. During the charging and discharging process, lithium ions can be inserted into and detached from the lattice structure of SnSe, enabling the storage and release of electrical energy.
VI HALBLEITERMATERIAL GmbH (VIMATERIAL) employs a stringent quality assurance system to ensure the reliability of our product quality. Strict quality control is implemented throughout the entire production chain, and for defective products, we strictly enforce the principle of rework and redo. Each batch is released only after passing detailed specification tests.
Every batch of our materials is independently tested, and, if necessary, we send samples to certified companies for testing. We provide these documents and analysis certificates with the shipment to certify that our products meet the required standards.
