To provide a method for manufacturing a ceramic product having excellent heat resistance by recycling a waste insulator.
In order to avoid the problem that when the waste insulator is crushed, a cap within the insulator breaks at the same time and cement (mortar) bonding metal or pin fittings enters and deteriorates fire resistance, when a waste insulator is coarsely crushed by a jaw crusher, the distance of an opening of the jaw crusher is made larger than a metal fitting part fixed by cement on the waste insulator. As a result, the metal fitting part passes through the jaw crusher without breakage. The metal fitting part is then removed from the coarsely crushed product and the resulting coarsely crushed product of the waste insulator is pulverized up to such a particle size as to enable compacting and sintering. This waste insulator pulverized product is compacted and fired to obtain a heat resistant ceramic product.
