Porous ceramics & catalyst carriers

    Product Inquiries

Porous ceramics & catalyst carriersPorous ceramics are used as catalyst carriers and filter media in various forms. Catalyst carriers are used in the petrochemicals industry, while filter media are used for water and waste liquid treatment. Noritake has established technologies for controlling pore size distribution and specific surface areas in a sophisticated manner.
