Abstract
A method for making a ceramic body is provided wherein the ceramic components are joined in their green state. The method includes applying heat to the surfaces to be joined to cause a localized melting of the binder. The surfaces are then brought together and joined by alternately applying compression and stretching. The method is particularly advantageous for forming unitary ceramic arc tube bodies for high intensity discharge (HID) lighting applications.
