Ultra-lightweight Alumina Bubble Bricks: the best choice for cathode furnaces. With the widespread application of lithium-ion battery cathode materials, lithium-ion battery cathode material manufacturers are facing increasing pressure to conserve energy and reduce emissions. Traditional Ultra-lightweight Alumina Bubble Bricks used in cathode material furnaces have a bulk density of at least 1.5, high thermal conductivity, and poor insulation. Furthermore, they are difficult to cut and process during construction, resulting in high energy consumption and production costs. Lithium-ion battery cathode material furnace manufacturers urgently need Lightweight Alumina Bubble Bricks that offer better energy efficiency and insulation while reducing production costs.
Ultra-lightweight Alumina Bubble Bricks
Ultra-lightweight Alumina Bubble Bricks possess excellent high-temperature resistance and thermal insulation properties, making them suitable for direct application in the working layer of lithium battery kilns. They significantly reduce furnace weight, improve structure, save materials, energy, and reduce costs. Technical parameters of Ultra-lightweight Alumina Bubble Bricks: bulk density 0.8±0.05g/cm³, alumina content >99%, linear shrinkage ≤1% (1500℃*6h), thermal conductivity [w/(m.k)] 0.26 (400℃ hot surface temperature), room temperature compressive strength ≥3MPa
Advantages of Ultra-lightweight Alumina Bubble Bricks
- Lower bulk density. Traditional 99% Alumina Bubble Bricks have a bulk density of at least 1.5. Compared to traditional products, ultra-lightweight Alumina Bubble Bricks significantly reduce furnace weight, saving materials, energy, and costs.
- Compared to traditional 1.5 bulk density 99% Alumina Bubble Bricks, it exhibits better thermal shock stability.
- Its thermal conductivity is extremely low, only 30% of traditional products. The thermal conductivity of a traditional 1.5 bulk density 99% Alumina Bubble Brick at 400 degrees Celsius is 0.78 on the hot surface. Lower thermal conductivity means better insulation; the insulation effect of ultra-lightweight Alumina Bubble Bricks is three times that of traditional bricks. The same furnace layer thickness allows for lower cold surface temperatures, resulting in greater energy savings, or the ability to make the insulation layer thinner.
- Superior on-site cutting and processing performance. It can be cut and processed arbitrarily according to the actual on-site conditions, just like cutting and processing mullite bricks. Traditional products have poor cutting and processing performance and are difficult to cut and process on-site.
Compared to traditional Alumina Bubble Bricks, ultra-lightweight Alumina Bubble Bricks offer superior energy efficiency and insulation, along with unique product advantages, significantly reducing production costs for lithium-ion battery cathode material manufacturers and their kilns. They are undoubtedly the best choice for refractory and insulation applications in lithium-ion battery cathode material kilns.
