Abstract
A heating apparatus, a non-combusted heating device and a method for manufacturing the same are disclosed. In certain aspects, the heating apparatus includes a casing with an end for receiving a product to be heated, a heating element at least partially disposed within the casing, and an insulation layer formed between an internal surface of the casing and an external surface of the heating element. The insulation layer includes a polycrystalline material having a valve metal oxide.
Claims24
A heating apparatus for use with a non-combusted heating device, comprising:
- a casing with an end for receiving a product to be heated;
- a heating element at least partially disposed within the casing;
- and
- an insulation layer formed between an internal surface of the casing and an external surface of the heating element,
- wherein the insulation layer is configured to electrically insulate the heating element from the casing and permit heat transfer from the heating element to the casing, and the insulation layer comprises a continuous oxide layer disposed on and in contact with at least one of the internal surface of the casing or the external surface of the heating element,
- wherein the at least one of the internal surface of the casing or the external surface of the heating element comprises a valve metal, and
- wherein the continuous oxide layer of the insulation layer comprises a polycrystalline material having a valve metal oxide, a metal of the valve metal oxide being the same as the valve metal of the at least one of the internal surface of the casing or the external surface of the heating element.
