BURNED ASH PARTICLE, ORGANOSILICON MATERIAL, ABRASIVE, AND METHOD FOR MANUFACTURING ORGANOSILICON MATERIAL

摘要

PROBLEM TO BE SOLVED: To provide burned ash particles which are effectively utilizable as various kinds of materials.;SOLUTION: Burned ash particles are sorted from burned ash of woody biomass which has been burned by a circulation type fluid bed boiler. The burned ash particles have a structure in which a surface is covered by a calcium-containing material around silicon derived from fluid sand added upon combustion. Further, a particle diameter of 125 to 500 μm is sorted. A sulfur content is 1.2 wt.% or less. The burned ash particles are usable as an organosilicon material for raw material of an abrasive, and so forth, for example.;SELECTED DRAWING: Figure 4;COPYRIGHT: (C)2018,JPO&INPIT
