Adaptable ceramic based microwave absorbing heater

Abstract

An “Adaptable Ceramic Based Microwave Absorbing Heater” simple to manufacture with efficiency to capture and store enough microwave energy in typically one to 1.5 minutes in a 1200 W microwave oven to keep food or beverages hot at the table when the heater is used in a “Heat Retentive Plate” or “Heat Retentive Coffee Mug” and other dinnerware. The heater can also be used for scorching or browning food and in other industrial applications.

1 . An adaptable ceramic based microwave absorbing heater for absorbing microwave energy, storing it as thermal energy and radiating in the infrared wave length or radiated heat, comprising: a rigid, heat resistant, semi conductive ceramic, for providing the thermal mass and the path for internal currents; 
 a conductive metal particles, for producing induction heating and heat due to agitation of polar molecules, uniformly embedded to said ceramic; and    a conductive trace of carbon, for creating a path for electric current, uniformly dispersed to said ceramic.    
     
     
         2 . A rigid microwave-absorbing material comprising a uniformly dispersed mixture of metal particles, polar molecules, carbon and a hardened ceramic binder filling the interstices, 
 Whereby a Hardened and strong matrix with relatively high thermal mass and adjustable micro wave absorbing capacity is provided.
