Mullite
Mullite supplied by Gongyi City Hong The Refractory Material Co., Ltd. is an aluminum silicate refractory material with aluminium oxide content ranging from 60 % to 75 %. The product is produced in China and conforms to international refractory standards. It is offered in powder and granular forms suitable for high‑temperature applications. The supplier lists the material as meeting ISO and SGS verification.
Typical commercial mullite exhibits a bulk density of 2.5 - 2.8 g cm‑3 and a thermal conductivity of 1.5 - 2.0 W m‑1 K‑1, values that are standard for high‑temperature ceramics. The material’s coefficient of thermal expansion lies between 4.5 and 5.5 × 10‑6 K‑1, providing low expansion during rapid temperature changes. Such properties make it a reliable choice for kiln furniture and furnace linings where dimensional stability is critical.
End users include manufacturers of ceramic tiles, glass melting furnaces and steel casting molds who require refractory components that resist thermal shock. The supplier can ship under FOB or CIF terms from the Zhengzhou port, and packaging is typically 25 kg bags or bulk containers. Buyers should confirm the exact mesh size, any required certifications and the minimum order quantity directly with the supplier before placing an order.

Sourcing Mullite from Gongyi City Hong The Refractory Material Co., Ltd. - China Import Guide
Before placing an order, verify Gongyi City Hong The Refractory Material Co., Ltd.’s business registration and request copies of any ISO or SGS certificates that cover the mullite product. Ask for a recent mill test report that confirms aluminium oxide content, purity and bulk density, as these parameters directly affect performance in high‑temperature environments. Ensuring the supplier’s documentation matches the specifications reduces the risk of receiving off‑grade material.
Confirm the shipping terms early - the supplier can ship FOB Zhengzhou or CIF to your destination port. Inquire about the expected lead time for production and loading, and negotiate payment terms such as a confirmed letter of credit. Clarify whether the cargo will be loaded in 25 kg bags or bulk containers, and verify any freight forwarder preferences to avoid unexpected charges.
Arrange a third‑party inspection at the loading port to check particle size distribution, packaging integrity and compliance with the stated specifications. Require a certificate of analysis and a compliance statement for the HS 2528 classification to facilitate customs clearance. Retain all inspection reports and certificates as part of your import documentation for future reference.
