Use of a paste containing precious metals for the production of browning dishes for microwave ovens

摘要

Metal coatings for browning dishes to be used in microwave ovens are obtained by use of plastes of: (a) 50 to 80% by weight of a mixture of (aa) 5 to 70% by weight of a conductive component formed of 5 to 95% by weight ruthenium oxide, and the balance being at least one of silver, palladium, rhodium oxide and/or bismuth oxide, (bb) 30 to 95% by weight of a glass frit (b) 20 to 50% by weight of an organic binder. Coatings which are applied to glass, ceramic and/or vitreous ceramic dishes and cooking vessels are very adherent and in a few minutes reach temperatures of up to 300 DEG C.
