Buy & Import Crucible Liners from Shanghai Spark Advanced Material Co., Ltd - Wholesale Supply

The crucible liners offered by Shanghai Spark Advanced Material Co., Ltd are fabricated from a fused silica and alumina composite, commonly referred to as an Al2O3-SiO2 blend. The material composition delivers excellent thermal shock resistance and structural integrity for processes that exceed 1600°C. Each liner is supplied with full quality certification documentation, as stated in the supplier’s product description. The product is marketed for use in metallurgy, foundry work and high-temperature laboratory applications.

Typical industry specifications for this class of liner include a density of about 2.2 g/cm³ and a thermal conductivity near 0.8 W/m·K, values that align with standard fused silica-alumina grades. Standard dimensions frequently range up to 300 mm length, 200 mm width and 50 mm thickness, although the supplier notes the possibility of custom sizes on request. The composite’s melting point is around 1700°C, providing a safety margin above the operating limit. Low thermal conductivity helps to minimise heat loss, improving energy efficiency during repeated heating-cooling cycles.

Typical buyers include metal foundries, precious-metal refiners and research laboratories that require reliable, repeatable casting performance. Orders are handled as bulk exports, with packaging options such as palletised bulk or 20 kg bags, and the supplier can supply the required documentation for ISO and CE compliance. Prospective importers should confirm minimum order quantities, incoterms and payment terms directly with the supplier before finalising the purchase.

Frequently Asked Questions About Crucible Liners from Shanghai Spark Advanced Material Co., Ltd
The liner is made from a fused silica and alumina composite, specifically an Al2O3-SiO2 blend. This composition provides high thermal shock resistance and is standard for liners used above 1600°C.

Sourcing Crucible Liners from Shanghai Spark Advanced Material Co., Ltd - China Import Guide

Before placing an order, verify that the material composition matches the fused silica-alumina blend described, and request copies of the ISO and CE certificates to ensure compliance with your market standards. Confirm the exact dimensions, whether standard or custom, and check that the packaging format meets your handling requirements. It is also advisable to ask for a material data sheet that lists density, thermal conductivity and melting point for quality assurance.

When arranging shipment, ask the supplier to specify the preferred Incoterms, such as FOB or CIF, and obtain an estimated lead time based on the agreed quantity and customisation level. Payment terms are typically negotiated per transaction; common arrangements include a letter of credit or advance payment, but the exact method should be clarified in advance. Clarify any freight forwarding preferences and whether the supplier can assist with customs documentation for imports into your country.

Implement a pre-shipment inspection based on ISO and CE standards to verify that the liners meet the specified thermal and mechanical properties. Request a third‑party test report covering thermal shock resistance and dimensional tolerances, especially for custom sizes. Upon arrival, compare the received certificates and test reports with the supplier’s documentation to confirm that the product complies with the agreed specifications.
