Automotive Cordierite Ceramics

Golcha Minerals talc in automotive cordierite ceramics


Golcha Minerals talc beneficial for diesel particulate filters and catalytic supports.


Application of talc in ceramics has an essential role to play. It supports in processing the fine usage of talc so as to make automotive cordierite ceramics the best in terms of usage. The main raw material used in automotive cordierite which further produces ceramic honeycomb element in diesel particulate filters (DPF) and catalyst supports. All these features make the usage of talc better. There are several reasons in which talc can hold up talc has advantageous effects while extrusion, body preparation, firing and even on the characteristics of final constituent.


Talc grants artifact pore structure at the right temperature profile for DPF and catalysts. Its features also assists decisive lubrication while extrusion at the slight walls. It puts in to vital rheology while extrusion, green body drying and mixing.


This application requires extremely untainted lamellar talc consisting of low Cao and particular particle size. In consideration to catalysts: mix of platy and microcrystalline talc will bestow with superb performance. Other than this for DPF: The most preferred is platy talc. We also provide talc for thin wall, ultra sleek walls and standard wall structures.



The talc is very beneficial for body preparation, extrusion and firing, and the final component. When fired at the correct temperature profile, it confers a relic pore structure to the catalyst or the DPF. During extrusion, the talc provides critical lubrication to the thin walls and also makes important contribution to critical rheology during mixing, extrusion and green body drying.


Other than this, when it comes to surface area, chemical composition and particle size allocation the Golcha Minerals products in case of automotive cordierite are configured for consistency. This is accomplished through proper utilization of proprietary milling technology, vigilant ore selection and beneficiation.


Catalytic supports and diesel particulate filters are immensely benefited by using this talc. It is the most important raw material, used for producing the ceramic honeycomb component in diesel particulate filters (DPF) and catalyst supports.


For this application, lamellar talc with specific particle size, low CaO content and high purity is required. While platy talk is preferred for the DPF, a blend of microcrystalline and platy talc will be used for the catalysts. The supply line of our products include standard wall, thin-wall and ultra-thin-wall structures.


All the products for automotive cordierite are produced with a very high level of engineering and uniformity regarding particle size distribution, surface area and chemical composition. All this is achieved through careful ore selection, beneficiation and proprietary milling technology. The HON-50, HON-350 and HON-150 grades are recommended for this application.
