Abstract
The present invention relates to a susceptor combination comprising: metallic particles; particles of at least two or more semiconductor materials; and one or more alkaline or alkaline earth metal salts; to a susceptor ink composition containing it. It also relates to a laminate comprising a dielectric substrate and the susceptor ink composition printed on the substrate, as well as a microwaveable package comprising the laminate.
Claims11
A susceptor ink composition comprising a susceptor combination and one or more carriers,
- wherein the susceptor combination comprises;
- metallic particles, wherein the metallic particles are selected from the group consisting of nickel, zinc, copper, aluminum, and mixtures thereof;
- particles of at least two semiconductor materials, wherein the semiconductor materials are selected from the group consisting of carbon black, titanium carbide, silicon carbide, zinc oxide, and mixtures thereof;
- and
- one or more alkaline metal salts, wherein the one or more alkaline metal salts comprise a cation and an anion;
- wherein the cation is selected from the group consisting of Na+ and K+;
- and wherein the anion is selected from the group consisting of Cl− and F−;
- wherein the amount of the susceptor composition comprises from 6.7% to 40% by weight of the total weight of the susceptor ink composition.
A susceptor ink composition comprising a susceptor combination and one or more carriers, wherein the susceptor combination comprises;
- metallic particles,
- particles of at least two semiconductor materials, and
- one or more alkaline metal salts;
- wherein the susceptor combination comprises:
- aluminum, carbon black, silicon carbide, and sodium chloride.
