Copper Telluride lumps are lumpy compounds consisting of copper and tellurium, usually black or grey in appearance, with semiconducting properties, which have potential applications in the fields of thermoelectric materials, photovoltaic materials, and electronic devices, and need to be stored in a suitable environment in order to keep their properties stable.
VIMATERIAL supplies high purity Copper Telluride lumps , we supply Copper Telluride lumps with stable performance and low impurity content, we have professional technical team, please contact us if you need.
Analytical formula: Cu₂Te
Molecular weight: 254.692g/mol
Appearance: usually lumpy, the colour may be grey-black, with a certain metallic luster.
Density: about 7.27g/cm³.
Melting point: 900°C
Crystal structure: Cu₂Te has a specific crystal structure, belonging to the tetragonal crystal system. The copper and tellurium atoms in the crystal structure are arranged according to a certain pattern, and the copper and tellurium atoms interact with each other through chemical bonding to form a stable crystal structure, which gives Cu₂Te certain physical and chemical properties, and makes it show unique properties in electricity, optics, and other aspects.
Solar cell field: can be used as an important raw material for the preparation of high-performance thin film solar cells, such as copper indium gallium selenide solar cells, help to improve the photoelectric conversion efficiency of the battery.
Thermoelectric materials: In thermoelectric materials, the thermoelectric properties can be optimised through the formation of nanocrystals, etc., to achieve efficient interconversion of heat and electricity.
Nanoelectronic devices: Due to their high electrical conductivity and photoresponsiveness, CuTe can be used to manufacture nanoelectronic devices, such as high-performance photodetectors.
Industrial manufacturing: Tellurium in Cu₂Te lumps can improve the workability of copper, so Cu₂Te lumps can be used as an industrial raw material to improve the workability of copper products.
Each batch of products implement the strictest quality control system, we have completed product records, product traceability with strict quality assurance. We have a complete process for the handling of non-conforming products, and will not flow the non-conforming products to the next process. We provide samples for customers’ re-inspection, and we also support the third party inspection organisations designated by customers.
Copper Telluride lumps are packed in double vacuum bags or double bags and then bottles. The minimum packaging unit is 100g/bottle.
Copper Telluride lumps should be stored in a dry, cool, well-ventilated and sealed environment, avoiding contact with humid air, strong acids, strong bases and oxidising substances, and preventing violent physical impacts to maintain the stability of its physical and chemical properties.
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.
