METHOD OF MANUFACTURING FILTER ELEMENTS WITH CERAMIC ACTIVE LAYER ON POROUS CARBON SUPPORT Russian patent published in 2003 - IPC

Abstract RU 2205061 C1

FIELD: filtering engineering. SUBSTANCE: manufacture of ceramic membrane is characterized by applying adhesion-active suspension layer on porous carbon support followed by drying and heat treatment, after which ceramic active layer is laid onto adhesion-active suspension layer and the total is dried and calcined. Suspension is composed of, wt %: metallic silicon 30-40, activator (sodium chloride) 5-10, binder (fine phenol- formaldehyde resin powder) 4.5-5.5, and silicon dioxide to 100. EFFECT: increased adhesion of active oxide layer to carbon support. 3 cl, 2 tbl
