SiCヒーター
Abstract:
(EN)
This SiC heater is provided with: a heating element which comprises a silicon carbide sintered body in the form of a thin plate and an insulating coating film formed on the surface of the silicon carbide sintered body; a pair of electrodes for having an electric current pass through the heating element; and a heater base which holds the heating element from one surface side, while blocking the heat from the heating element. The insulating coating film is arranged on a surface of the silicon carbide sintered body, said surface being on the reverse side of the heater base-side surface, and has an electric specific resistance at room temperature of 10
9
Ω·cm or more and a thermal expansion coefficient of from 2 × 10
-6
/K to 6 × 10
-6
/K (inclusive). The insulating coating film uses SiO
2
as a matrix, and contains 1% by weight to 35% by weight (inclusive) of a first additive component that contains at least one of B
2
O
3
and Al
2
O
3
and 1% by weight to 35% by weight (inclusive) of a second additive component that contains at least one of MgO and CaO.

La présente invention concerne un dispositif de chauffage en SiC qui est pourvu : d'un élément chauffant qui comprend un corps fritté en carbure de silicium sous la forme d'une plaque mince et un film de revêtement isolant, formé sur la surface dudit corps fritté ; d'une paire d'électrodes servant au passage d'un courant électrique dans l'élément chauffant ; d'une base de dispositif de chauffage qui porte l'élément chauffant depuis un côté de surface tout en bloquant la chaleur provenant de l'élément chauffant. Le film de revêtement isolant est disposé sur une surface du corps fritté en carbure de silicium, ladite surface se trouvant sur le côté opposé de la surface côté base du dispositif de chauffage, et présente une résistance électrique spécifique, à la température ambiante, supérieure ou égale à 10
