PRODUCTION METHOD OF POWDER FOR MICRO WAVE-ABSORPTION HEATING UNIT, POWDER FOR MICRO WAVE-ABSORPTION HEATING UNIT, AND MICRO WAVE-ABSORPTION HEATING UNIT WITH THE SAME

摘要

PROBLEM TO BE SOLVED: To provide powder for a micro wave-absorption heating unit which is made of a substance of white color and is capable of effectively absorbing micro waves to generate heat.

SOLUTION: The method comprises the step of sintering a mixture of powdered raw materials including 50 mass% or less of silicon oxide (not including 0 mass%) in terms of SiO2, and 50 mass% or more of zinc oxide (not including 100 mass%) in terms of ZnO in a temperature range between 750°C and 1350°C inclusive.
