The present invention discloses a process for sintering particles using a sintering aid. The sintering aid can be brought into contact with a plurality of particles to be sintered such that a mixture of the particles and the sintering aid is provided. The mixture of particles and the sintering aid is heated and at least part of the sintering aid is vaporized. Sintering of the particles to form a sintered component followed by cooling of the sintered component can complete the process, or in the alternative, a subsequent heating step or steps can be included whereby additional vaporization of the sintering aid can occur.
