Porous Ceramics
Porous ceramics have many excellent properties, such as high temperature resistance, chemical corrosion resistance, and high porosity, and are widely used in filtration and separation, catalyst carriers, and pollution prevention and control.
Cordierite
Cordierite is a colorless, blue, light blue, gray-blue or smoky blue silicate mineral with chemical composition of 2MgO 2Al2O3 5SiO2, melting point of 1460℃, low thermal expansion coefficient, good Chemical stability and dielectric properties.
Cordierite porous ceramics not only has the properties of cordierite, such as low thermal expansion coefficient, good chemical stability, dielectric properties and other properties, but also has the good performance of porous ceramics, such as low density, high permeability, corrosion resistance, high temperature resistance, good thermal insulation, etc.
Applications of cordierite porous ceramics
Catalyst Support Materials
Cordierite porous ceramic catalyst carrier can improve the efficiency of the catalyst, and the main mechanism is to make the catalyst have a proper shape and better mechanical strength in the catalytic reaction, so that the trace amount of the catalyst can be uniformly dispersed.
At present, honeycomb cordierite porous ceramic carrier is most used in the automobile industry, which has the advantages of thin wall, high porosity, high mechanical strength, good thermal stability, and impact resistance.
Filter separation material
The filtration and separation of gas and liquid can be realized by utilizing the characteristics of porous ceramic pore size and uniform size distribution.
Refractory
Cordierite porous ceramics can be used as a refractory material due to its low thermal expansion rate and strong thermal shock resistance.
Electronic Device Materials
Cordierite porous ceramics can be used as a material for electronic devices due to its good dielectric properties.
