<P>PROBLEM TO BE SOLVED: To provide a method for purifying an amorphous silica from a grain husk for ensuring at a low cost a source of supplying of a highly reactive amorphous silica without using a low fluid sodium silicate water solution or the like as a silica source, a method for manufacturing an inorganic curable composition utilizing this method, and a method for manufacturing an inorganic cured product. <P>SOLUTION: By firing the grain husk including largely the amorphous silica under a predetermined condition, the amorphous silica is taken out while the condition of the amorphous silica is kept, and by using this as a silica source, it is unnecessary to use the low fluid sodium silicate water solution or the like as the silica source, and this problem on the fluidity can be solved. <P>COPYRIGHT: (C)2012,JPO&INPIT |
