Detailed Product Description
Our Alumina Bubble Brick is made from high purity hollow alumina spheres combined with strong binders. This unique structure creates a lightweight brick that keeps your furnace walls strong without adding extra weight. The hollow spheres trap air, giving the brick excellent insulation that helps cut down on heat loss and boost energy efficiency.
The manufacturing process includes melting raw materials at high temperatures, blowing them into tiny hollow spheres, and then carefully shaping and firing the bricks to lock in their durability and thermal performance. This approach produces a tough, lightweight refractory brick that excels in high-temperature environments, making it a smart choice for energy-saving insulation in your furnaces.
Technical Specifications
| Property | Value | Standard Test Method |
|---|---|---|
| Chemical Composition | Al2O3 ≥ 99% | ASTM C799 |
| Bulk Density | 1.2 g/cm³ | ASTM C133 |
| Thermal Conductivity | 0.15 W/m·K at 800°C | ASTM C177 |
| Max Service Temperature | 1825°C | ASTM C411 |
| Compressive Strength | 15 MPa | ASTM C133 |
| Thermal Shock Resistance | Excellent (≥25 cycles) | ASTM C155 |
Our Gotrays Alumina Bubble Brick offers a high-purity 99% Al2O3 composition, ensuring durable and reliable performance in extreme heat environments. The lightweight bulk density of 1.2 g/cm³ makes it ideal for reducing furnace structure weight. Thermal conductivity stays low even at high temps, helping keep energy costs down. Its maximum service temperature of 1825°C meets demanding industrial needs, while strong compressive strength delivers long-lasting support. Plus, excellent thermal shock resistance keeps it stable through rapid temperature changes common in U.S. industrial setups.
Physical Properties and Dimensions
Our Alumina Bubble Brick comes in standard sizes like 230x114x65mm, making it easy to fit into most furnace and kiln setups. We also offer custom sizing options to meet specific project needs, so you can get the right fit without compromise.
The brick’s unique structure features closed-cell hollow alumina spheres, which you can see in detailed diagrams and images. This design gives the brick its ultra-lightweight nature while providing excellent insulation and thermal shock resistance. The tiny sealed bubbles trap air, reducing density to about 1.2 g/cm³ without sacrificing strength.
This combination of size flexibility and advanced structure makes Gotrays Alumina Bubble Brick a top choice for energy-efficient furnace insulation across many high-temp applications.

Installation and Handling Guide
Installing Gotrays Alumina Bubble Brick is simple when you follow these easy steps:
- Dry Lay First: Arrange the bricks without mortar to check the fit and layout.
- Use Compatible Mortar: For permanent setups, choose a high-temperature, alumina-based mortar that matches our brick’s specs.
- Handle With Care: Although ultra lightweight, these bricks are still fragile. Avoid dropping and handle gently to prevent cracks.
- Safety Gear: Always wear gloves, safety glasses, and a dust mask when cutting or handling bricks to protect yourself from dust and sharp edges.
- Sealing Joints: Make sure joints are tightly sealed to maintain insulation and prevent heat loss.
- Curing Time: Allow mortar to cure properly based on product instructions before exposing bricks to full heat.
