Alumina Reticulated Foam Filter

Alumina Reticulated Foam Filter

The influence of the sintering phase transformation process, sintering properties and mechanical properties of Alumina Reticulated Foam Filter.
The organic precursor impregnation method is suitable for preparing articles with high porosity and interpenetrating pores, and the process is simple and the cost is low.
The choice of precursors during the preparation process, the firing temperature and the holding time all affect the properties of the final product.
The compression and flexural strength of the Alumina Reticulated Foam Filter decreases with increasing porosity.

The main crystalline phase of alumina porous ceramics is corundum.
Taking a Alumina Ceramic Foam Filter prepared from a precursor of 30 ppi as an example, the alumina foam ceramic having a porosity of 88.9 vol % has a compressive strength of 3.31 MPa and a flexural strength of 1.69 MPa.
The alumina foam ceramic having a porosity of 86.8 vol % has a compressive strength of 3.50 MPa and a flexural strength of 1.91 MPa.
