Japanese Patent JPH0233674

Kind Code:

B2

Abstract:

This invention comprises a method of ultrasonically end-capping a tubular green body which comprises a mixture of 40-60 volume percent sinterable beta''-alumina precursor particulate and 60-40 volume percent organic sacrificial binder wherein said sacrificial binder comprises a thermoplastic elastomer, a plasticizer which may be oil, wax or oil and wax, stiffening polymers, a processing aid and optional components. The tube is preferably formed by extrusion molding. The green body tube may be end-capped by ultrasonic forming or by ultrasonic bonding of an end-cap to the tube. During this process, ultrasonic vibration energy is dissipated as heat energy which melts the thermoplastic binder composition and welds the joining surfaces.
