Abstract
The purpose of the present invention is to provide a thermoelectric conversion element having a film which not only maintains sufficient adhesion even when exposed to a high temperature but also exhibits excellent oxidation resistance and crack resistance. The problem is solved by a thermoelectric conversion element including a thermoelectric conversion component, in which the thermoelectric conversion component contains magnesium silicide and/or manganese silicide and is covered with a film containing Si and Zr.
Claims4
A method for producing a thermoelectric conversion element, comprising a thermoelectric conversion component, comprising:
- a pretreatment step of contacting the thermoelectric conversion component with a pretreatment agent that comprises a phosphoric acid compound and water, and
- a film forming step of contacting the thermoelectric conversion component after the pretreatment step with a surface treatment agent that comprises Si and Zr ions to form a film comprising Si and Zr,
- wherein the thermoelectric conversion component comprises magnesium silicide and/or manganese silicide, and
- wherein a ratio (ZM/SM) of a Zr mass (ZM) to a Si mass (SM) in the film is in a range of 0.25 to 0.59.
