Abstract

Abstract Translated from Japanese (57)【要約】 【目的】レニウムを含有するセラミックヒータの電極メ ッキ工程におけるセラミック表面へのメッキの付着を防 止する。 【構成】セラミックの未焼成のグリーンシートに印刷す る金属抵抗体用のペーストに使用されるレニウム粉末と して、示唆熱分析において250℃〜350℃の範囲で 発熱ピークを示さないものを用いることで、焼成後のセ ラミック中にレニウムの拡散が見られないセラミックヒ ータを製造することが出来る。これによってセラミック 表面に達したレニウムを核としたメッキの付着が無くな り、清浄なセラミック表面のセラミックヒータを製造す ることが出来る。 (57) [Summary] [Purpose] To prevent the adhesion of plating to the ceramic surface in the electrode plating process of the ceramic heater containing rhenium. [Structure] As a rhenium powder used in a paste for a metal resistor printed on an unfired green sheet of ceramic, by using a rhenium powder that does not show an exothermic peak in a range of 250 ° C to 350 ° C in a suggested thermal analysis, It is possible to manufacture a ceramic heater in which the diffusion of rhenium is not seen in the ceramic after firing. As a result, the adhesion of the plating having rhenium as a nucleus reaching the ceramic surface is eliminated, and a ceramic heater having a clean ceramic surface can be manufactured.
