Aluminiumoxid-Keramik-Schaumstoffziegel Beschreibung
Aluminiumoxid ceramic foam bricks are light ceramic structures produced from aluminium oxide based materials. They have a cellular structure with interconnected pores that provide a high surface area to volume ratio.
The bricks exhibit resistance to corrosion and to corrosion by molten aluminium, thereby removing inclusions. They have a low mass and low thermal conductivity, which leads to a reduced accumulation of thermal energy and an energy-saving effect. Their dimensions are precisely controlled to increase construction speed and to ensure the structural strength and stability of the masonry.

Aluminiumoxid-Keramik-Schaumstoffziegel Anwendungen
Alumina ceramic foam bricks are essential components in various industrial applications. They are employed as linings in furnaces, kilns and other high-temperature installations to minimise heat losses and to maintain stable operating temperatures during heat treatment and metal casting processes. In foundries, the bricks protect crucibles and pans from thermal shock and ensure uniform temperature distribution during casting. They are used in heat exchangers, boilers and industrial ovens, thereby reducing energy consumption and operating costs. In construction, they contribute to fire protection by enhancing the fire resistance of structural elements and improving building insulation. They are also utilised in environmental control systems and thermal solar collectors to improve heat storage and energy efficiency. In electronics and semiconductor manufacturing, the bricks support thermal management, which helps to maintain stable operating conditions and reliable processes.
