Mouldable composition and methods for producing moulded bodies therefrom

A mouldable composition comprises a mixture of 40-60 volume percent sinterable beta sec -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, stiffeni...

Beschreibung
Zusammenfassung:	A mouldable composition comprises a mixture of 40-60 volume percent sinterable beta sec -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. Composition may be compression moulded or extruded into tubes which may be end-caped by ultrasonic forming or by ultrasonic bonding of an end-cap to the tube. During the latter process, ultrasonic vibration energy is dissipated as heat energy which melts the thermoplastic binder composition and welds and joining surfaces.
