摘要： A method for determining a sintering shrinkage of a pre-sintered body. The method includes providing a green preform with at least one design feature. The green-preform is pre-sintered to form a white body. At least one change in the at least one design feature with the pre-sintering is recorded. An expected sintering shrinkage to a dense-sintered component is determined using the recorded change.

摘要： The tensile loading of a ceramic-metal joint, made by shrink-fit locking a cylindrical ceramic component into a flange of ferrous material in the axial direction of the ceramic component can be improved by undersizing the diameter D of the bore of the flange by 13-27 .mu.m making it, at room temperature, this much smaller than the diameter d of that part of the ceramic component to be attached to the flange by shrink-fit locking, by preparing the cylindrical surface of the said part of the ceramic component with a surface roughness Ra of 0.05-0.2 .mu.m and the surface of the bore in the flange with a roughness Ra of 0.4-0.8 .rho.m, and by heating the flange, before fitting it to the ceramic part, to a temperature such that, after fitting together the ceramic component and the flange, the resultant stresses produced on cooling the assembly to room temperature are below the yield strength R.sub.po.2 of the ferrous material, and the said temperature of heating is below the Wohler temperature of the ceramic material.

摘要： A process for the production of a ceramic prosthesis by forming a blank from a mixture of zirconium oxide and hafnium oxide of between 94.8% and 95.3% by weight, yttrium oxide of between 4% and 5.2% by weight, and any further oxide as a balance of less than 1% by weight, with a monoclinic proportion of below 5% by volume. The blank is put into the shape of the required prosthesis by means of a rotating tool of metallically bound diamond grains, using specific operating parameters for the tool.
