Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
The invention claimed is: 1. 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. 2. The method for producing a thermoelectric conversion element according to claim 1 , wherein the surface treatment agent is obtained by mixing an alkali metal silicate (A), a cerium oxide-stabilized zirconium oxide (B), and a component (C) that comprises at least one selected from metal oxide particles and clay minerals except for the alkali metal silicate (A) and cerium oxide-stabilized zirconium oxide (B). 3. The method for producing a thermoelectric conversion element according to claim 1 , wherein the thermoelectric conversion component comprises polycrystalline magnesium silicide and/or polycrystalline manganese silicide. 4. A method for producing a thermoelectric conversion module, comprising a step of providing a plurality of the thermoelectric conversion element obtained by the method for producing a thermoelectric conversion element according to claim 1 , and a step of connecting the plurality of the thermoelectric conversion elements.
