Ovenware for microwave ovens which contain a composition comprising a ferrite susceptor which has a Curie point temperature of about 100~C to 300~C and a thermoplastic or thermoset polymer are improved and said composition is in contact with the food or drink to be heated or cooked, and/or composition has a thermal conductivity of 0.7 W/m~K or more. Heat generated by absorption of microwave radiation by the susceptor is more readily conducted to the food being cooked when the thermal conductivity of the composition is high, particularly when the part containing the susceptor is relatively thick. The ovenware and food being cooked. Also described are designs for various pieces of ovenware containing this composition.
L~invention concerne des plats pour fours à micro-ondes améliorés contenant une composition comprenant un suscepteur de ferrite ayant une température de point de Curie d~environ 100°C à 300°C et un polymère thermoplastique ou thermodurci, ladite composition étant au contact de l~aliment ou de la boisson à chauffer ou cuire, et/ou ladite composition ayant une conductivité thermique supérieure ou égale à 0,7 W/m°K. La chaleur générée par absorption de radiation micro-ondes par le suscepteur est acheminée plus facilement à l~aliment en cours de cuisson lorsque la conductivité thermique de la composition est élevée, en particulier lorsque la pièce contenant le suscepteur est relativement épaisse. Elle décrit également des conceptions de divers articles de vaisselle contenant ladite composition.
