Zhengzhou Sunrise Refractory Co., Ltd. supplies natural sillimanite (Al2SiO5) bricks that convert to a mullite (3Al2O3·2SiO2) structure when fired above 1500 °C. The bricks are classified as high‑alumina refractory and exhibit low thermal expansion. According to the supplier description, the bricks possess a dense structure and good thermal‑shock resistance. These characteristics make them suitable for lining high‑temperature furnaces.
In the refractory market, sillimanite bricks are commonly produced in sizes of 250 × 250 × 300 mm, although custom dimensions can be requested. Typical compressive strength for this grade ranges from 30 to 40 MPa at 1500 °C. Standard porosity is below 5 % and bulk density is usually around 2.4 g/cm³. The material’s inherent corrosion resistance to slag and alkali attack aligns with the supplier’s claim of superior durability.
Major users include steel plants, cement kilns, glass melting furnaces and ceramic kilns, where the bricks line arches, forehearth superstructures and bushings for rochwool. Importers typically require verification of the brick dimensions, density and thermal‑shock test results before confirming an order. The supplier lists no minimum order quantity or lead‑time, so buyers should request these details directly. Payment and Incoterms are also to be agreed with Zhengzhou Sunrise Refractory prior to shipment.

Before placing an order, verify the brick dimensions, bulk density and thermal‑shock test results against your process requirements. Request a detailed material data sheet and, if possible, a sample for in‑house testing to confirm performance under your furnace conditions. Clarify whether the supplier can provide certificates that meet ISO 9459 or equivalent standards.
Logistics for shipments from Zhengzhou typically involve sea freight from major Chinese ports. Confirm the preferred Incoterm (for example FOB Zhengzhou or CIF Shanghai) and ask the supplier for estimated lead‑time based on your order volume. Payment terms such as T/T in advance or LC at sight should be negotiated and documented before production begins.
Quality assurance is critical for refractory imports. Arrange a third‑party inspection to check dimensions, density and visual defects before loading. Ask the supplier to provide inspection reports, X‑ray diffraction data confirming mullite formation, and any applicable export documentation required by your country's customs authority.
