High Quality Silica Brick
The product is a quality Silica Brick supplied by Zhengzhou Sunrise Refractory Co., Ltd. in China. It is an acid refractory brick composed of silica (SiO2 > 94%) together with tridymite, cristobalite and a glass phase. The bricks have a true density of 2.34 g/cm³ and can withstand a melting temperature under load of 1620‑1670 °C. At 1450 °C the overall linear expansion is between 1.5 % and 2.2 %, providing tight joints. Size tolerance is reported as accurate, with a pure colour and luster appearance.
Silica bricks are normally manufactured from natural silica sand that contains more than 96 % SiO2, a composition that gives high resistance to acidic slags. Typical industry grades are supplied in standard dimensions of 229 × 114 × 114 mm and show compressive strengths of at least 30 MPa, thermal conductivity around 1.5 W/m·K and porosity of 5‑10 %. The material’s low thermal expansion and good thermal shock resistance make it suitable for continuous‑operation furnaces where temperature cycling is common.
These bricks are widely used in the roof and superstructure of glass melting furnaces, in coke oven chambers, and as refractory linings in steel‑making kilns. Buyers are glass manufacturers, steel producers and other high‑temperature processing plants that require durable acid‑resistant linings. Export‑grade packaging is offered; however, exact minimum order quantities, lead times and incoterms are not listed and should be confirmed directly with the supplier.

Sourcing quality Silica Brick from Zhengzhou Sunrise Refractory Co., Ltd. - China Import Guide
Before placing an order, verify the silica content exceeds 94 %, confirm the reported true density of 2.34 g/cm³ and request laboratory data on linear expansion and compressive strength. These parameters determine suitability for acid‑slag environments and long‑term service life.
Logistics for bulk refractory bricks typically involve freight from Zhengzhou ports under FOB or CIF terms; however, the supplier has not disclosed specific incoterms, lead times or payment conditions, so these should be clarified in the purchase agreement. Ensure that packaging is suitable for heavy loads and that stacking instructions are followed to avoid damage during transit.
Arrange a third‑party inspection prior to shipment to check dimensions, density and visual defects. Request certificates of analysis for SiO2 content and thermal‑expansion test results. Confirm that the export packaging meets international handling standards to protect the bricks throughout the shipping journey.
