  • Microwave absorbing heater
    Patent number: 5189273
    Abstract: A microwave absorbing heater comprising a porous body containing silicon oxide and having a porosity of 40 to 95%.A microwave absorbing heater may be formed of a porous body having a porosity of 40 to 95% and composed of an inorganic electrical insulating material, and a silicon carbide film formed on the surface thereof.Since the microwave absorptivity is high, the dissipation of water from a heated object is easy and the heat dissipation is small, the heating efficiency is great. The thermal shock resistance is also high.
