Refractory Basic Alumina Insulation Brick
The Refractory Basic Alumina Insulation Brick supplied by Zhengzhou Ruitai Refractory Materials Technology Co., Ltd. is a composite of alumina, magnesia and calcia designed for insulation in high‑temperature kilns and furnaces. The brick’s material composition is an Alumina‑Magnesia‑Calcia (Basic Alumina) composite, providing refractoriness in extreme heat. It is employed in the sintering zone of cement clinker and lime production as well as in copper‑smelting furnaces. The product is intended for the insulation layer of equipment and large‑diameter pipes.
Basic alumina bricks typically contain 70‑85 % Al₂O₃, 10‑20 % MgO and 5‑10 % CaO, giving a density around 2.2‑2.5 g/cm³ and a compressive strength of 10‑15 MPa. Their porosity of 30‑45 % contributes to a thermal conductivity of 0.5‑0.7 W/m·K at 1000 °C, which reduces heat loss in continuous processes. The standard size for such bricks is 230 mm × 115 mm × 70 mm, although custom dimensions can be produced on request. These typical values align with industry standards for basic alumina insulation products.
Industrial users such as copper smelters, cement clinker plants and lime‑sintering facilities commonly purchase this brick to improve energy efficiency and protect furnace linings. Because the listing does not disclose minimum order quantity, price or lead time, interested buyers should contact Zhengzhou Ruitai directly to confirm trade terms. Verification of material certificates and performance test reports is recommended before finalising any contract.

Sourcing Refractory Basic Alumina Insulation Brick from Zhengzhou Ruitai Refractory Materials Technology Co., Ltd. - China Import Guide
Before placing an order, verify the exact chemical composition and density of the brick by requesting a recent certificate of analysis and a material test report. Confirm that the product complies with any national or project‑specific refractory standards that apply to your plant.
Discuss logistics early by agreeing on Incoterms, typical lead times and payment conditions. The supplier indicates a response rate of 0 % on the platform, so direct communication is essential to confirm shipping arrangements, container loading plans and any freight forwarder preferences.
Arrange a third‑party inspection at the factory or upon arrival to check dimensions, surface integrity and physical performance. Request documentation such as a test report for compressive strength, thermal conductivity and porosity, and keep records of any agreed‑upon acceptance criteria.
