<p>An insulator is produced by a step of forming a calcium silicate hydrate such as tobermorite or xonotlite by mechanochemical treatment of silica with calcium hydroxide for synthesis, a step of forming graphite oxide by reacting graphite with a mixed acid, a step of forming a slightly expanded graphite by washing the graphite oxide with water, a step of forming a composite material of the calcium silicate hydrate with the slightly expanded graphite by mixing the calcium silicate hydrate with the slightly expanded graphite produced in the above-mentioned steps, a step of drying the composite material as is in powder form or after it is molded, and a step of calcinating the composite material in powder or molded form. The insulator is used as a general insulator or a core material for a vacuum insulator.</p> |
