By providing a sealing system for bonding which incorporates a sealing cement and at least three spacers disposed within said sealing cement, two members can be easily and securely bonded together with a precise separation gap between them and with the lateral flow of the sealing cement precisely controlled. Preferably, spherical spacers are employed having a diameter equal to the spacing desired between the members being joined, and the sealing cement incorporates a thermal expansion compatible with the thermal expansion of the members being joined.
