초록
In this study, diatomite based materials were investigated as a support filter for silica particle coating. Thesilica sol for coating was synthesized by a stöber process. The diatomite support was dry-pressed at 10 MPa and sinteredat 1200oC for 1 hour. The coating sol was prepared as a mixture of EtOH and silica sol. The diatomite supportwas coated by a dip-coating process. Silica coated diatomite filter was sintered at 1000~1200oC for 1 hour. The largestpore size was decreased with increasing concentration ratio of coating sol. The gas and water permeability of silicacoated diatomite decreased with increasing of concentration ratio of the coating sol.
