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. FOCUS has established technologies for controlling pore size distribution and specific surface areas in a sophisticated manner.
