Abstract: The present invention relates to a heat resistant composition which exhibits excellent heat and wear resistances after being cured. Further, it has excellent releaseability and durability, and the cured film thereof has a more excellent stability than a prior art adhesive of this type, by preparing it from two components: a powder mixture consisting of 20% by weight or more of zirconium oxide, 1 to 10% by weight of sodium titanate, 2 to 15% by weight of yttria based on the zirconium oxide and the balance of silica; and a sodium silicate containing a small amount of water added thereto.
