JIG FOR SINTERING ELECTRONIC PARTS

摘要

PURPOSE:To provide a jig used at the time of sintering electronic parts by forming a layer which reacts hardly with the electronic parts and has such a structure as to prevent easy exfoliation even under heat history on the surface of a substrate by thermal spraying. CONSTITUTION:An alumina-based thermally sprayed layer as a first layer is formed on the surface of an aluminous or aluminous-siliceous substrate having >=85wt.% Al2O3 content and a thermally sprayed layer of unstabilized zirconia as a second layer is further formed on the first layer to obtain a jig for sintering electronic parts.
