Fuel cell field: as a good p-type semiconductor material, it can be used to prepare electrode materials for fuel cells.
Each batch is subject to strict quality control standards, with perfect data records and complete product traceability mechanism. Each batch of our products can provide samples for customers to re-inspection.
Copper Selenide granules are packed in double vacuum bags or double vacuum bottles, and the minimum packing unit is 100g.
Copper Selenide granules should be stored in a dry, cool, well-ventilated environment, tightly sealed, away from air, water, acids and strong oxidizing agents, and away from heat and ignition sources to prevent oxidation, moisture, and chemical reactions that could alter its 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.
