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 surface 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.
L'invention porte sur un procédé de fabrication de corps en céramique par réunion d'éléments de céramique à l'état vert consistant: à chauffer les surfaces de jonction desdits éléments pour faire fondre localement le liant, puis à mettre en contact puis unir lesdites surfaces en les soumettant alternativement à de compressions et des étirements. Le procédé est en particulier intéressant pour former des corps monolithiques de tubes à décharge pour éclairage par lampes à décharge à haute intensité.
