This new structural material is the world's advanced low-temperature and clean sintering technology through international cooperation between China and Russia (the world-renowned chemistry and high-temperature material expert Yuri Alexandrokov academician); China Innovation No. 2003CO12W, adopts a three-dimensional network shape Structure, better than honeycomb foam type, with high opening rate, low filtration resistance, small normal static difference, high surface energy, strong adsorption of impurities, superior thermal shock resistance, high strength, no slag (ceramsite), etc. advantage. It is widely used in the filtration and purification of aluminum melt in the aluminum processing industry to better improve the quality of aluminum materials and expand its application in environmental protection engineering, heat energy utilization, and catalytic carriers.

　　Production control and quality assurance system:

　　1. Control of the pore size of the foam mesh: confirm the pore size of the foam mesh, and use a high-power magnifying glass for batch sampling inspection.

　　2. The accuracy of the ingredients, the uniformity in the mixing, the viscosity detection of the slurry, and the accuracy of the trapped material.

　　3. Control of drying process.

　　4. Temperature gradient control during sintering.

　　5. Evaluation of filter plate quality: light transmittance, microscopic blind hole detection, compressive strength, thermal shock resistance, etc.
