  1. Question

    What ceramics have the property of emitting infrared rays (wave length) when it was warmed?

    All ceramics and indeed all materials emit infrared rays (heat) when they are warm. There are no ceramics that have any advantage in terms of their infrared emission. If anyone tells you so, or if they make health claims for special ceramics, they are fooling you.
