Problems solved by technology

Then, the cutting powder is removed in a cleaning process, etc., but the removability of the fixed cutting powder is low, and it is difficult to achieve the high cleanliness required for electronic materials
In addition, it is difficult to obtain the flatness of the surface of the thermoelectric conversion element due to the precipitation of ionic components contained in the cleaning agent or the oxidation of the thermoelectric conversion element.

Embodiment

[0087] Hereinafter, the present invention will be more specifically shown by way of examples. The following examples do not limit the present invention, and inventions whose designs are changed as conditions change are also included in the technical scope of the present invention.

[0088] (1) Test materials

[0089] Cut from the sintered body of magnesium silicide (sintered body doped with Sb (0.5at%) and Zn (0.5at%)) ingot, prepare a columnar body for the thermoelectric conversion part of 3 mm × 3 mm × 6 mm, as a test Material e1.

[0090] The sintered body of the above-mentioned doped magnesium silicide is mixed with 61.12g of Mg, 35.31g of Si, 2.32g of Sb, and 1.26g of Zn, and the mixture is heated at 1400K and then slowly cooled, thereby obtaining a sintered body doped with Sb and Zn Mg 2 Si sintered body ingot.

[0091] It was cut out from a sintered (undoped) ingot of manganese silicide, and a columnar body for the thermoelectric conversion part of 3 mm x 3 mm x 6 m...

Abstract

The purpose of the present invention is to provide a thermoelectric conversion element having a film that maintains sufficient adhesion even when exposed to a high temperature, and has excellent oxidation resistance and crack resistance. The problem is solved by a thermoelectric conversion element provided with a thermoelectric conversion part, wherein the thermoelectric conversion part is coatedwith a film which contains magnesium silicide and / or manganese silicide, and also contains Si and Zr.

Description

technical field [0001] The invention relates to a thermoelectric conversion element and a thermoelectric conversion module with the thermoelectric conversion element. More specifically, it relates to a thermoelectric conversion element usable as a thermoelectric conversion mechanism such as a thermoelectric power generation device, and a thermoelectric conversion module including the thermoelectric conversion element. Background technique [0002] Conventionally, as thermoelectric materials, thermoelectric power generation elements, Peltier elements, and the like capable of mutually converting heat energy and electric energy are known. Thermoelectric power generation using thermoelectric materials has the advantage of being able to convert heat energy directly into electricity without moving parts, and is used in watches that operate at body temperature and power supplies for space. In particular, thermoelectric power generation used in automobiles, home appliances, inciner...
