Applications
Optical field: Because Yttrium Fluoride has good optical properties, it can be used in the preparation of optical films, laser crystals and so on. For example, it plays an important role in rare-earth crystal laser materials and upconversion luminescent materials, and it can also be used to manufacture fluoride glass optical fiber and fluoride spinning glass.
Lighting field: Yttrium Fluoride can be used to manufacture carbon electrodes for arc lamps in lighting sources.
Material Preparation: It is one of the raw materials for the electrolytic production of yttrium metal.
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.
