Silica Bricks
Silica Bricks supplied by Zhengzhou Huachen Refractory Co., Ltd. are acidic refractory bricks whose composition contains a minimum of 93% silicon dioxide (SiO2). The bricks soften at temperatures between 1640 and 1680 °C and exhibit strong resistance to acidic slags such as those containing CaO, FeO and Fe2O3. The supplier notes that the material is prone to oxidation by alkaline oxides and that rapid temperature changes below 600 °C can cause volume expansion.
In the refractory industry, silica bricks with 93% or higher SiO2 are considered high‑grade and are typically dense, with a bulk density around 2.2 g/cm³ and compressive strengths near 30 MPa. Their thermal shock resistance is relatively low, so gradual heating and cooling are standard practice. Standard brick dimensions are 230 mm × 115 mm × 65 mm, giving a typical weight of about 8 kg per unit, which matches the supplier's export‑grade packaging description.
These bricks are most commonly used in coke ovens, hot‑blast stoves, and the crown or superstructure of glass melting furnaces, making them essential for steelmaking and glass manufacturers. Buyers usually import them in bulk on wooden pallets secured with steel strapping, and they must confirm the exact minimum order quantity, lead time and preferred Incoterms with the supplier before placing an order.

Sourcing Silica Bricks from Zhengzhou Huachen Refractory Co., Ltd. - China Import Guide
Before placing an order, verify the silicon dioxide content and request a recent chemical analysis report. Confirm the exact brick dimensions, weight and packaging method, and ask the supplier to provide any applicable refractory standards certificates. Checking these details helps ensure the product meets the technical requirements of your furnace design.
Discuss logistics early by asking the supplier for estimated lead time, preferred Incoterms such as FOB or CIF, and the nearest shipping port. Clarify the minimum order quantity and whether partial pallets are acceptable. Understanding payment terms, including any required advance deposits, will reduce the risk of delays during the procurement process.
Arrange a third‑party inspection before loading to validate dimensions, density and compressive strength against the supplied specifications. Request a full set of test reports, including thermal shock and chemical resistance tests, as part of the shipping documents. Maintaining these quality checks and proper documentation will support smooth customs clearance and reliable performance in the field.
