摘要： A process for the preparation of an article by powder injection molding, the process including the steps of providing a feedstock containing a powder of a ceramic, a metal or a metal alloy dispersed in a binder, heating the feedstock, and injecting the heated feedstock into a mold cavity of a mold, where it cools and hardens to the configuration of the mold cavity. The process is characterized in that step c) is carried out under the application of vibrational energy onto the feedstock.

摘要： A powder injection molding apparatus including an injection unit, mold formed of two mold parts with parting surface between first and second mold part, enclosing in assembled state of mold a mold cavity fluidically connected with injection unit via transfer channel, vibrational energy generator and transducer, and clamping unit designed to retain under the effect of clamping force first and second mold parts in contact with each other. Apparatus is characterized in that first and second mold parts include a first and second retaining hole, respectively, each extending essentially perpendicularly to parting surface and arranged opposite to each other respective to parting surface, clamping unit includes first and second pin each extending essentially perpendicularly to parting surface, wherein first and second pins cooperate in assembled state of mold with retaining portion of first and second retaining holes, respectively, to retain first and second mold parts in contact with each other.

摘要： A body made of a ceramic material stabilized by a stabilizing agent and a process for preparing the body. The body includes a surface region extending from the surface of the body to a predetermined depth. The stabilizing agent is enriched in the surface region. The proportion of the stabilizing agent in the surface region continuously increases from the predetermined depth to the surface. The process includes applying the stabilizing agent to the surface of a basic body made of a ceramic material and heating the basic body with the stabilizing agent applied thereon at a temperature such that at least a portion of the stabilizing agent diffuses into the ceramic material.

摘要： A process for the preparation of a sterilized ceramic body including or essentially consisting of stabilized zirconia of a defined colour, including the steps of: providing a ceramic primary body including or essentially consisting of stabilized zirconia of a first colour A, and sterilizing the primary body using radiation sterilization whereby the primary body undergoes a colour change to a colour B. The process includes the further step of irradiating the sterilized primary body with electromagnetic radiation of at least one wavelength lying in the wavelength band ranging from 150 nm to 700 nm to induce an at least partial reversal of the colour change to obtain a colour C of the sterilized ceramic body, the colour C complying with the following requirements in the CIELAB colour space: L* being from 54 to 95, a* being from −15 to 15 and b* being from −15 to 15.
