Product Description
Lightweight Thermal Insulation Hollow Ball Insulating Alumina Bubble Brick for Industrial Furnace
Brief Introduction of Alumina Bubble Brick:
Alumina Bubble Brick is a kind of high temperature insulating material, which is composed of melting and blowing alumina bubble with compound additive, shaped by vibrating technique and sintered at high temperature.
Application of Alumina Bubble Brick:
It's mainly used for insulation layer of furnace and kiln, and also can be used for service linings in manufacturing high-purity quartz for the electronics industry such as ceramic tile linings in gas turbines and backup linings in reactors.
Feature of Alumina Bubble Brick:
- High Service Temperature
- High Purity
- Low Thermal Conductivity
- Low Bulk Density
- High Mechanical Strength
Dimensions of Alumina Bubble Brick:
The standard sizes of them are 230*114*65mm and 230*114*76mm. Except for the common sizes, some special shapes could be customized according to the customers' requirements.

Packaging & Shipping
Packing Method:
a. Bricks will be stacked on the export wooden pallets in order;
b. There will be paper sheets between each layer of bricks;
c. Orderly placed refractory bricks are wrapped around by plastic film to be waterproof;
d. Eventually the four sides and top will be reinforced with plywood to prevent collisions;
e. Pallet size no more than 1100x1100x1100 mm.
