VITROCÉRAMIQUE UTILISÉE COMME SURFACE DE CUISSON POUR CHAUFFAGE PAR INDUCTION, PRÉSENTANT UNE MEILLEURE CAPACITÉ D'AFFICHAGE EN COULEUR ET UNE MEILLEURE PROTECTION THERMIQUE, AINSI QUE PROCÉDÉ DE FABRICATION DE LADITE SURFACE DE CUISSON

摘要

A glass ceramic as cooktop for induction heating having improved colored display capability and heat shielding is provided. The cooktop includes a transparent, dyed glass ceramic plate having high-quartz mixed crystals as a predominant crystal phase. The glass ceramic contains none of the chemical refining agents arsenic oxide and/or antimony oxide and has a transmittance values greater than 0.4% at at least one wavelength in the blue spectrum between 380 and 500 nm, a transmittance >2% at 630 nm, a transmittance of less than 45% at 1600 nm, and a light transmittance of less than 2.5% in the visible spectrum.
