Gadolinium Sulfide
Gadolinium sulfide from Zegen Metals & Chemicals Ltd. is a yellow crystalline powder, a compound of the rare earth metal gadolinium with sulfur. The product carries CAS number 12134-77-9 and EC number 235-217-1, with a molecular formula of Gd2S3 and a molecular weight of 416.728 g/mol. Its density is 6.1 g/cm³, a key parameter for optical and industrial applications where material consistency is critical.
This rare earth sulfide is typically produced in controlled environments to ensure purity and stoichiometric balance, with gadolinium in the +3 oxidation state. Gadolinium sulfide is part of a family of lanthanide sulfides known for their stability and optical properties, often used in specialized applications such as infrared windows or as a component in phosphors. The material is sensitive to moisture and should be stored under inert conditions to prevent degradation.
Primary buyers include manufacturers of optical materials, research laboratories, and specialty chemical producers. As an optical material, it is valued for its transparency in specific infrared ranges. Sourcing this product from China offers access to a mature rare earth supply chain, but buyers should confirm handling protocols and purity specifications before ordering. Bulk shipments are typically packaged in sealed containers to maintain integrity during transit.

Sourcing Gadolinium Sulfide from Zegen Metals & Chemicals Ltd. - China Import Guide
Before ordering gadolinium sulfide from Zegen Metals & Chemicals Ltd., verify the exact purity level, particle size distribution, and trace impurity content. Optical applications often require materials with less than 10 ppm of transition metal impurities, which can affect transparency. Request a certificate of analysis and, if possible, a sample for third-party testing to confirm suitability for your use case.
Confirm logistics details such as packaging, which should be airtight and moisture-proof, and incoterms like FOB or CIF for shipments from China. Lead times for rare earth compounds can vary significantly based on production schedules, so clarify expected delivery timelines and any seasonal constraints. Payment terms should be negotiated in advance, with consideration for secure methods such as letters of credit for first-time buyers.
Quality checks should include X-ray fluorescence (XRF) or inductively coupled plasma (ICP) analysis to verify composition and purity. For optical applications, transmittance tests across the intended wavelength range are essential. Ensure all documentation, including material safety data sheets (MSDS) and certificates of origin, is provided with the shipment. Inspection upon arrival is recommended to confirm the material matches the agreed specifications.
