Silica Brick
Silica Brick supplied by Henan Hongtai Kiln Refractory Co., Ltd. is an acid‑resistant refractory made from silica (SiO2) with a content of 93 % or higher. The bricks are designed for use in coke ovens, glass‑melting furnaces and various iron‑and‑steel processes where exposure to acidic slags is common. Their softening temperature ranges from 1 640 °C to 1 680 °C, allowing stable performance in high‑temperature zones. The material’s volume stability under heat makes it suitable for arch structures and other critical kiln components.
The product is a typical high‑silica refractory brick; standard dimensions in the industry are 228 mm × 114 mm × 76 mm, although custom sizes can be requested. Typical density is about 2.3 t/m³ and the compressive strength generally exceeds 30 MPa, providing reliable load‑bearing capacity. Thermal conductivity is around 1.5 W/m·K, which helps maintain temperature uniformity. While the brick resists acidic slags, it is vulnerable to alkaline oxides such as CaO, K2O and Na2O, a characteristic noted in standard refractory performance data.
End users include steel mills, glass manufacturers and coke‑plant operators who require durable lining material for high‑temperature, acid‑rich environments. Henan Hongtai packages export‑grade bricks on wooden pallets wrapped in waterproof film to protect against moisture during shipment. Prospective buyers should confirm minimum order quantities, lead‑time and preferred Incoterms directly with the supplier before finalising any contract.

Sourcing Silica Brick from Henan Hongtai Kiln Refractory Co., Ltd. - China Import Guide
Before placing an order, verify the SiO2 content by obtaining a recent mill test report and confirm the brick’s acid‑slag resistance through a chemical analysis. Check that the dimensions and packaging method match your project’s handling equipment, and request a sample if possible to assess fit and finish. These checks help avoid mismatches that could affect furnace performance.
Logistics for the Henan supplier typically involve shipment from Xinmi Port, with common Incoterms such as FOB or CIF. Lead‑time is not disclosed in the listing, so ask for an estimated production and dispatch schedule. Payment terms are usually negotiated directly and may include a deposit via T/T followed by balance on document presentation; confirm the exact terms before signing the contract.
Implement a third‑party inspection before loading, focusing on SiO2 percentage, dimensional tolerance, and surface integrity. Request a certificate of compliance and any available test reports, such as compressive‑strength or thermal‑shock resistance data. Maintaining proper documentation will smooth customs clearance and ensure the bricks meet the required quality standards for your installation.
