Title:
METHOD FOR PRODUCING METALLIC AND CERAMIC HOLLOW BODIES
Document Type and Number:
WIPO Patent Application WO2005089985
Kind Code:
A3
Abstract:
The invention relates to a method for producing a hollow body comprising at least one metallic and/or ceramic component. According to said method, a binder is mixed with a ceramic and/or metallic powder (10). The viscosity of said mixture is set to a value in excess of 1,000 Pascal-seconds (12). The mixture is formed (14) into a tube (110) by means of one or more dies, said tube being formed (16) into a green compact by means of a blow moulding process. The green compact is converted (18) into a brown compact by the removal of the binder and said brown compact is in turn converted into the finished hollow body by means of a thermal treatment step (20).
