A recently granted patent (Publication Number: US11839714B2) discloses a method for making a heating unit. The method involves coating a portion of the interior surface of a conductive substrate with a slurry of solid fuel comprising a metal reducing agent, a metal containing oxidizing agent, and an inorganic binder. The slurry is then solidified, and electrodes are coupled to the conductive substrate and the surface of the solid fuel.

In one embodiment of the method described in the patent, the metal reducing agent can be selected from zirconium, titanium, aluminum, and iron. Additionally, the metal containing oxidizing agent can be chosen from MoO3, Fe2O3, MnO2, KClO4, and KClO3. Furthermore, the binder used in the process is specified to be an inorganic silicate-based binder. This patented method offers a novel approach to creating a heating unit with specific materials and processes, potentially leading to improved performance and efficiency in heating applications.
