Product Description
Alumina Bubble Bricks

Alumina Bubble Bricks for applications up to 1800°C/ 3270°F, these brick have excellent insulating properties
and high hot strengths. Bubble alumina bricks are made with tiny hollow insulating spheres made from highpurity
alumina (also called bubble alumina). Alumina does not exhibit high thermal conductivity, and when in the form
of hollow spheres, its thermal conductivity is additionally reduced. Both properties made Bubble Alumina brick an
excellent insulating material that can withstand exceptionally high temperatures. Typical applications for Bubble
alumina bricks include gas or electrically heated kilns and furnaces as well as glass making industries.

The insulating firebrick (IFB) that contain highalumina bubbles are often used as the working lining in ceramic
kilns, backup linings in gasifiers for coal and petroleum coke, gas/ oil (with heavy residue feed stock), and industrial waste. These IFBs are also used in hazardous waste and fluorine processing incinerators, hydrogen generators, auto thermal reactors for methanol production, and ammonia reformers.

Highpurity alumina hollow insulating spheres are designed to withstand high temperatures and demanding environments. These bubbles themselves are an important component in refractories used for many different applications, from insulating kiln brick and ceramic tile linings in gas turbines to backup linings in reactors and working linings in manufacturing high-purity quartz for the electronics industry.
