Lightweight Alumina Bubble Brick: Premium High-Temperature Insulation for Industrial Excellence
When you're operating high-temperature kilns, you need materials that won't let you down. Lightweight Alumina Bubble Brick from TY Refractory delivers exceptional performance where it matters most. With over 30 years of manufacturing expertise since 1986, we produce these advanced insulation bricks using melting and blowing industrial alumina. Our product achieves up to 1800°C service temperature while maintaining remarkably low thermal conductivity of 0.4–1.0 W/m·K at 1000°C. The unique micro-cellular structure reduces bulk density to just 0.8–1.5 g/cm³, yet delivers impressive cold crushing strength of 10-20 MPa. You'll benefit from our ISO 9001:2015 certified quality system and the technical backing of LuoYang Refractory Research College.
What Makes Our Alumina Bubble Brick Special?
You're looking at a progressive protection fabric that changes how high-temperature heaters perform.
Our item highlights high-purity alumina empty circles reinforced with progressed hard-headed folios. The result? A fabric that tackles your hardest challenges.
Key focal points you'll appreciate:
- Exceptional energy savings through superior insulation
- Direct flame contact capability up to 1800°C
- High chemical purity with ≥98% Al₂O₃ content
- Outstanding thermal shock resistance
- Significantly lighter than traditional dense refractories
Not at all like ceramic fiber items that debase rapidly, our brick keeps up auxiliary keenness all through its benefit life. You won't confront visit substitutions or startling downtime.
The round pore structure acts as a characteristic crack-arrestor. This implies your heater dividers remain intaglio indeed amid fast temperature changes.

Frequently Asked Questions
Can I use these bricks for direct flame contact?
Absolutely. Unlike many ceramic fiber products, our product has the density and structural strength for direct flame exposure up to 1800°C. You'll get working lining performance, not just backup insulation.
How do they compare to JM series insulation bricks?
You're getting significantly better performance. Our bricks offer higher purity (99% Al₂O₃ versus 60-80%) and much higher service temperature than JM28 or JM32 alternatives.
Are they resistant to hydrogen atmospheres?
Yes. The extremely low silica content makes them highly stable in reducing environments. Whether you're working with hydrogen or CO atmospheres, you won't see the silica reduction and integrity loss that affects other refractories.
What about custom shapes?
We stock standard 230×114×65mm bricks for quick delivery. For custom CNC-machined or molded shapes, you're looking at 4-6 weeks for precision firing and sizing. We'll work with your specifications.
Why the higher cost compared to traditional insulation bricks?
You're paying for specialized production. We electro-fuse alumina and blow it with high-pressure air to create the bubbles. Combined with high-purity raw materials for 1800°C performance, this delivers value through extended service life and energy savings.
How do you ensure consistent quality?
We follow rigorous inspection protocols including bulk density testing per ASTM C134, cold crushing strength validation, permanent linear change testing at 1600-1700°C, and XRF chemical analysis. Every batch meets our technical datasheet specifications.
