Dechen Chemical's technical service team has many years of experience in the lead salt industry, providing customers with full-process support from product selection and sample testing to specification confirmation and technical documentation. Whether for a first purchase or long-term cooperation, the team offers professional advice based on each customer's specific application.

1. Product Selection Support

The company's main products include red lead (Pb3O4), litharge (PbO), lead nitrate, fire assay flux and inorganic pigments. Different applications have different requirements for purity, particle size and other indicators. Based on the intended use — such as lead-acid batteries, piezoelectric ceramics, leaded glass or fire assay analysis — the technical team recommends the appropriate product grade, helping customers avoid waste caused by improper selection.

2. Samples and Trial Orders

Product samples can be provided for customer testing and verification. Samples and bulk cargo follow the same quality standards and inspection procedures. Small trial orders can be arranged flexibly, allowing customers to fully verify product suitability before formal purchasing.

3. Specification Confirmation and Custom Formulation

Specific technical indicators of red lead, litharge and lead nitrate can be confirmed according to customer requirements. Fire assay flux can be custom-formulated for the customer's sample types and analytical requirements, supplied together with assay-grade lead oxide (Au≤1ppb, Ag≤0.5ppm) to meet the low blank-value demands of gold, silver and other precious metal analysis.

4. Technical Documentation

COA (Certificate of Analysis), TDS (Technical Data Sheet), SDS (Safety Data Sheet) and other technical documents can be provided with shipments, meeting customers' incoming inspection, quality traceability and compliance requirements. For export orders, documents are prepared according to the destination country's requirements.

5. After-sales Technical Support

If any issue arises during product use, the technical team can help analyze the cause and propose improvements. Feel free to contact us by phone or online message at any time.
