Ceramic Foam Filter Used In Metallurgy And Casting
The foam ceramic filter was prepared by organic foam impregnation process.
Effect of additive SiO2 micropowder and CeO2 on SiC-alumina-based foam ceramic filter.
The orthogonal experiment was carried out and the performance of ceramics was tested. The results show that there is an optimal ratio between the amount of SiO2 fine powder and CeO2 added and the firing temperature.
The silicon carbide-alumina based foam ceramic filter prepared by using the optimum formula at 1380 ° C has a compressive strength at room temperature of 2.10 MPa and a thermal shock stability of 20 times.
