METHOD OF PRODUCING A SINTERED PRODUCT

摘要

A method of producing an at least partially sintered product, comprising introducing sinterable material into a mould or die and having at least one wall member which is adapted to produce a surface of the said product and which is microwave heatable, and subjecting said mould or die to microwave radiation so as to heat the mould or die and thereby effect at least partial sintering of the sinterable material, characterised in that the or each said wall member is made at least predominantly of microwave heatable material having a dielectric loss factor .epsilon."eff at the frequency of said microwave radiation of at least 0.1 and having a thermal conductivity of at least 10 Wm-1K-1.
