Cadmium Sulfide (CdS) from Shanghai Spark Advanced Material Co., Ltd is a II-VI semiconductor compound supplied as a yellowish powder with 99.99% purity, suited for thin-film solar cells, photoconductors, and photodetector manufacturing. The material is packed in export-standard fiber drums to ensure stability during international transit, with compliance to REACH and TSCA regulations for hazardous substances. Its high purity makes it ideal for electronic and renewable energy applications where consistency is critical.
As a direct bandgap semiconductor, CdS exhibits strong photoconductivity and is often used in heterojunction solar cells paired with materials like CdTe or Cu2S. Typical particle sizes for industrial-grade CdS powder range from 1 to 10 micrometers, with a hexagonal wurtzite crystal structure as standard. The material’s optical bandgap is approximately 2.42 eV at room temperature, a key parameter for thin-film applications requiring specific light absorption properties.
This powder is sourced by manufacturers in the electronics, solar energy, and pigment industries for applications such as photoresistors, light-emitting diodes, and decorative coatings. Trade terms require proper hazmat documentation, and buyers should request full SDS and purity certificates to ensure compliance with import regulations. The material’s stability in ambient conditions makes it suitable for long-term storage, provided it is kept in sealed, moisture-resistant containers.

Before ordering, confirm that Shanghai Spark Advanced Material Co., Ltd provides a Certificate of Analysis (CoA) for the CdS powder, including purity verification via ICP-MS or XRF and trace element analysis. Request particle size distribution data and XRD patterns to ensure the material meets your thin-film deposition requirements. Verify compliance with REACH and TSCA regulations, as these are mandatory for importing hazardous materials into most countries.
Logistics for CdS powder require hazmat-compliant packaging and documentation, including an SDS and proper labeling as a Class 9 hazardous substance. Discuss Incoterms such as FOB or CIF with the supplier, and clarify whether they can arrange customs clearance or if the buyer must handle it. Payment terms may favor advance payment or letter of credit due to the regulated nature of the product. Confirm lead times, as hazardous material shipments often face additional scrutiny at ports.
Quality checks should include visual inspection for color consistency and the absence of agglomeration, as well as third-party testing for purity and crystal structure if the supplier’s CoA is insufficient. Request a sample for pilot testing to validate performance in your specific application, such as thin-film deposition or photoconductor fabrication. Ensure all documentation, including the CoA, SDS, and compliance certificates, is reviewed by your technical and legal teams to avoid customs delays or end-use issues.
