新規多孔性粒体
Document Type and Number:
Japanese Patent JP4177569
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a novel porous granule that exhibits properties similar to white carbon, and that has improved oil absorbency, specific surface area, whiteness and wire wearability. SOLUTION: The new porous granule is prepared by immersing burned ash discharged from combustion equipment in an alkaline solution containing silicic acid and neutralizing the burned ash with an acid so that the burned ash is made to be included in a substance selected from the group consisting of silicic acid, a silicate and a mixture thereof. The new porous granule obtained by immersion-treating the burned ash discharged from the combustion equipment immersed with a substance selected from the group consisting of silicic acid, a silicate and a mixture thereof is provided. Also the new porous granule obtained by making the burned ash discharged from the combustion equipment be included in the particle of a substance selected from the group consisting of silicic acid, a silicate and a mixture thereof is provided.
