Molecular Formula: DyScO₃
Molecular weight: about 279.41 g/mol
Appearance: colorless to light yellow transparent single crystal (polished sheet usually has a mirror-like surface)
Density: about 6.3 g/cm³.
Melting point: ~2100°C (stable at high temperatures, no clear boiling point)
Crystal structure: orthorhombic chalcogenide structure (space group Pbnm), low lattice mismatch with common chalcogenides (e.g. SrTiO₃)
Dielectric constant: about 20-25 (excellent performance at high frequencies)
Coefficient of Thermal Expansion: Good match with various functional materials (e.g. ferroelectric, superconducting films)
Thin film growth: It is a common substrate material for the growth of complex oxide thin films such as high temperature superconductors (e.g. YBCO), ferroelectrics and magnets. Epitaxial growth of thin films on dysprosium scandinate substrates allows precise control of the structure and properties of the films, laying the foundation for a wide range of electronic, energy and optical devices.
VI HALBLEITERMATERIAL GmbH implements strict whole-process quality control and 8D problem solving mechanism to ensure products comply with REACH, ASTM and industry standards, and support sustainable development and supply chain traceability. The company is committed to providing customers with high-quality products and services by managing the entire process from R&D to delivery and adhering to the principle of reworking non-conforming products.
Dysprosium Scandate is packaged in special boxes and placed in special cartons after vacuum treatment to ensure transportation requirements, or can be packaged according to customer requirements.
Dysprosium Scandate substrates should be stored in a dry and dust-free environment, sealed and protected from light, avoiding moisture and surface contamination.
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.
