Title: Surface roughening of thermistor material, thermistor material, thermistor wafer, and thermistor element
Inventor: KAWAGUCHI YUKIO
IPC: H01C7/04
Filed: 1990-03-23
Abstract: PURPOSE:To prevent an electrode layer from peeling off and to improve reliability and durability with the surface easily roughened by making a thermistor material from a sinter which contains boron carbide, the matrix substance of aluminum oxide, and further a predetermined additive element as the continuity-forming substance. CONSTITUTION:A material which contains boron carbide, the matrix substance containing aluminum oxide, and a kind or more of additive elements selected out of V, Nb, Ta, Cr, Mo, W, Mn, Co, Ni, Cu, Zn, Ga, Sn, Pb, Sb, and Bi as the continuity-forming substance is used to compression-mold their mixture at room temperature, to sinter it in an oxygen atmosphere or non-oxidizing atmosphere, and to leave it to cool down into a thermistor material. A thermistor material thus obtained is treated by surface roughening. At least the electrode-forming zone of the surface of a thermistor sintered material is roughened to improve the adhesiveness of an electrode layer. At this time, relatively light surface roughening conditions allows sufficient surface roughening. Therefore, an electrode layer of high adhesiveness can be formed.
