The electrical resistivity of the composite with 20 vol% of Ag filler suddenly decreased from 10^5 to 10^1 Ω・m at about 300℃, in analogy with the CTR characteristic observed in VO_2 ceramics. It was assumed that this phenomenon was due to the high thermal expansion of the conducting filler in a low-thermal-expansion matrix: as the temperature increased, the conducting filler particles expanded to come into contact with one to another, resulting in a drop of resistivity at a critical temperature. The critical temperature varied with both the kind and the amount of metal filler., application/pdf}, pages = {122--126}, title = {金属-シリカガラス複合体のCTR特性}, volume = {109}, year = {2001}, yomi = {オオタ, トシタカ and ヒラシタ, ツネヒサ} }
