The crucible is made of high purity corundum with an aluminium oxide content of at least 99 %. Its chemical composition is 99 % Al2O3, 0.2 % R2O, 0.1 % Fe2O3 and 0.2 % SiO2. It shows a bulk density of 3.80 g/cm³, apparent porosity of 1 %, bending strength of 350 MPa and compressive strength of 12 000 MPa. The maximum service temperature is rated at 1800 °C and the dielectric constant is 2 at 1 MHz.
The material provides excellent thermal‑shock resistance and corrosion resistance to molten metals, which suits laboratory analysis, fire assay, metal smelting and coal analysis. Typical industry sizes range from 50 mm to 200 mm internal diameter, with a wall‑thickness tolerance of ±0.2 mm and a standard wall thickness of 5 mm. Standard export packaging uses individual kiln‑grade boxes with cushioning to prevent breakage during sea freight. The crucible complies with common refractory standards such as ISO 15594 for high‑temperature laboratory ware.
Metallurgical research labs, university analytical departments and small foundries use the crucible for high‑temperature melt tests. The supplier offers export‑ready packaging and can ship to Chinese ports under any Incoterm the buyer specifies. Minimum order quantities, exact lead times and payment terms are not listed and should be confirmed directly with Henan Hongtai Kiln Refractory Co., Ltd.

Before placing an order, verify the Al2O3 purity claim of ≥99 % and request a certificate of analysis that details the exact chemical composition. Confirm the internal diameter, wall thickness and any dimensional tolerance that are required for your equipment, and ask the supplier to provide a sample or dimensional drawing if possible.
Logistics should be clarified early: ask Henan Hongtai Kiln Refractory Co., Ltd. which ports in China are used for loading, the expected lead time for production and shipment, and the Incoterms they can accommodate. Payment terms are not disclosed in the listing, so request a formal quotation that outlines the required deposit, letter of credit or other methods accepted.
When the shipment arrives, arrange for a third‑party inspection to check for cracks, dimensional accuracy and compliance with the stated mechanical strengths. Request the supplier’s test reports for bending and compressive strength, as well as any certification that confirms ISO 15594 compliance. Proper documentation such as a material safety data sheet and a certificate of origin will facilitate customs clearance.
