Tungsten Crucible
Luoyang Kekai Tungsten & Molybdenum Technology Co., Ltd. in Henan, China manufactures sintered tungsten crucibles for high‑temperature processes. The crucibles are made from sintered tungsten powder with a minimum purity of 99.9 % and a measured chemical purity of at least 99.95 %. Standard dimensions for the sintered series range from 100 mm to 550 mm in diameter, 50 mm to 700 mm in height, and a wall thickness of 8 mm to 12 mm. Typical density of the material lies between 18.2 and 18.3 g cm⁻³, and the surface roughness does not exceed Rz 6.3 µm.
In addition to the sintered type, the supplier can produce stamped or forged tungsten crucibles, the latter offering wall thicknesses of 3 mm to 10 mm and densities up to 19 g cm⁻³. All crucibles are designed to operate below 2450 °C in vacuum or de‑oxidising atmospheres, a temperature limit common to refractory tungsten vessels. The high density and low surface roughness provide excellent thermal stability for molten metal contact and minimise contaminant migration. Custom shapes and dimensions are available on request, allowing integration into specialised sintering furnaces and crystal‑growth chambers.
Typical applications include semiconductor wafer processing, sapphire single‑crystal growth, rare‑earth metal extraction and advanced glass or ceramic production. Buyers such as equipment manufacturers and research institutes often require export‑grade wooden crates together with a full material certification. The listing does not disclose minimum order quantities, pricing or lead times, so prospective importers should contact the supplier directly to confirm these trade details.

Sourcing Tungsten Crucible from Luoyang Kekai Tungsten & Molybdenum Technology Co., Ltd. - China Import Guide
Before placing an order, importers should obtain the latest material certification that confirms the tungsten purity, density and surface‑roughness values reported in the specification sheet. Request a sample of the raw tungsten powder or a test piece to verify the sintering quality, especially if the application involves ultra‑pure semiconductor processes. Verify that the supplier’s harbour‑level trust tier aligns with your risk assessment and that the company can provide traceability records for each batch.
The buyer should clarify the preferred Incoterm, as the listing does not state whether FOB, CIF or EXW applies. Lead time depends on the chosen dimensions and any custom machining; typical manufacturing cycles for standard sizes range from several weeks to a few months, so confirm the schedule before committing to a production run. Payment terms are not disclosed, therefore negotiate a secure method such as a letter of credit that protects both parties during the transaction.
During production the supplier uses density and hardness testing equipment, but buyers are encouraged to arrange an independent third‑party inspection prior to shipment. An on‑site audit can verify that the surface‑roughness and dimensional tolerances meet the stated specifications. Ensure that the export documentation includes the material certificate, a test report and any required customs declarations for tungsten goods.
