摘要：To produce a hollow ceramic product, a green ceramic mass is compressed to form a green moulded product and is sintered. In this process, at least two green moulded products are produced from the same ceramic mass, preferably rotationally symmetrically, with projections. After fitting together, the projections of the one moulded product enclose the projections of the other moulded product. The pressing density of the enclosing moulded product is less than that of the enclosed moulded product. <IMAGE>
