Product Description

Foam ceramics is made of porous ceramic foam body, is in the precursor of the original pores in the absorption of ceramic slurry as a skeleton, after drying, firing and become, the removal of three-dimensional network structure of the organic precursor, then the formation of a high rate of open pores (80% ~ 90%). Small density (0.2 ~ 0.5g/cm3), large specific surface area, small pressure loss, with a network structure of the porous body.

Product Characteristics

1、Foam ceramics have high specific surface, as a catalyst carrier can increase the effective contact area, enhance the catalytic effect;.
2、Because of its heat resistance, non-pollution, not easy to be poisoned, low cost and other advantages, it has been widely used in the chemical industry and other fields to deal with the problem of
It has been widely used in the chemical industry to deal with toxic, malodorous and other harmful gases.
3、The closed air holes in the foam ceramics reduce the exothermic efficiency and the convection in the heat propagation.
Convection, it has low thermal conductivity, thermal shock resistance and other excellent characteristics, is an excellent heat-resistant materials.

Physical and Chemical Properties

Classification of Foam Ceramics

Foam ceramics can generally be categorized into two types, namely open-cell (reticulated) ceramic materials as well as closed-cell ceramic materials, depending on whether the individual pores have solid walls or not.

Applications of Foam Ceramics

In the metallurgical industry aluminum, copper and other alloys casting, foam ceramics can be used as a filter material to filter out the oxidized ash slag. Foam ceramic filter plates can be used in sand and metal molds, and can be placed flat or standing.
