The Graphite Crucible offered by Jiangxi Ningheda Material Co., Ltd is manufactured from high-purity graphite containing more than 99% carbon, available in clay‑bonded or resin‑bonded composite form. It is engineered to resist thermal shock and oxidation, enabling reliable operation at temperatures up to 3000 °C when used in inert or reducing atmospheres. The design targets jewellery and precision metalworking, supporting the melting of gold, silver, platinum and other non‑ferrous alloys. The supplier indicates that custom sizes can be produced to match specific production requirements.
In the graphite crucible market, typical high‑purity grades exhibit densities between 1.8 and 2.0 g/cm³ and porosities of 5‑10 percent, which contribute to their thermal conductivity of 80‑120 W/m·K. Standard wall thickness ranges from 5 to 20 mm with dimensional tolerances commonly set at ±0.5 mm, allowing consistent fit within furnace chambers. Clay‑bonded composites are favoured for their ease of machining, while resin‑bonded variants provide marginally higher oxidation resistance in aggressive environments. These typical industry characteristics align with the specifications highlighted by the supplier, ensuring the crucible meets conventional performance expectations.
Buyers such as precious‑metal refiners, dental laboratories and small‑scale foundries typically select this crucible for its temperature capability and material stability. The supplier mentions flexible minimum order quantities and offers both FOB and CIF shipping terms, but exact MOQ and lead‑time should be confirmed directly. Prospective importers are advised to request the supplier’s certification documents and verify the agreed dimensions before finalising the contract.

Before placing an order, verify the carbon purity, maximum temperature rating and any dimensional customisations you require. Request a material test report and ask for copies of the supplier’s certification documents to ensure the crucible meets your quality standards. Confirm that the agreed specifications are clearly written in the purchase agreement.
Discuss logistics early by asking the supplier to confirm the preferred Incoterms, such as FOB or CIF, and to provide an estimated lead‑time based on your order size. Payment terms, including any advance deposit and balance settlement method, should be agreed in writing before production begins. Clarify whether the supplier can arrange container loading at the nearest port in China for a smoother shipment process.
Upon arrival, inspect the crucibles for surface cracks, dimensional accuracy and any signs of oxidation. Arrange for an independent laboratory to verify carbon content if the purity is critical to your process. Ensure that the supplier supplies a mill test report, material safety data sheet and a certificate of conformity alongside the commercial invoice.
