Alumina ceramic foam.

Alumina ceramic foam filter. With its excellent resistance to attack and corrosion from molten aluminum it can effectively remove inclusions reduce trapped gas and provides laminar flow and then the filtered metal is significantly cleaner. Alumina foam filter description. Foam ceramics are the third generation porous ceramics which are newly developed after ordinary porous ceramics and honeycomb ceramics.

Alumina ceramic foam insulation can be used as the heat insulating layer of the refractory lining on the hot side especially the high temperature reducing atmosphere furnace 1850 c it can be used for a long time under 1800 c air and reducing atmosphere. Alumina foam filter is mainly for filtration of aluminum and aluminum alloys in foundries and cast houses. Alumina ceramic foam insulation high purity alumina foam insulation brick for 1800 applications tecfoam tm is a high purity alumina ceramic foam with closed cellular structure low density high strength and excellent thermal shock resistance giving its an important role in high temperature insulation applications. The main component of the insulation is a microsphere made from alumina.

A ceramic foam with 90 vol of alumina showed the highest. Meanwhile yeast was used as pore former agent and ovalbumin as a binder to bind the particles and encouraging foam formation. Alumina ceramic foam filter is mainly for the filtration of molten aluminium and alloys in foundries and. Porosity 4 10mm thickness open cell al aluminium foam sheet.

Alumina foam insulation applications. With the excellent resistance to attack and corrosion from molten aluminum the filter can effectively remove inclusions reduce trapped gas and provide laminar flow and then the filtered metal is significantly cleaner. Ultra light sizal cell is designed for high temperature applications up to 1800 c. Ceramic foam filters general description of ceramic foam filters ceramic filter foams is just developed as a new type molten metal filters to decrease casting flaw in recent years play a vital role in the metal casting and foundry industries where they are used to filter out impurities in molten metal to improve the quality and performance of the end product.

50 to 90 vol of alumina was used with zeolite of clinoptilolite type. Alumina zeolite ceramic foam was demonstrated.
