SOLID ELECTROLYTE BODY FOR GAS SENSOR ELEMENT, MANUFACTURING METHOD THEREOF AND GAS SENSOR ELEMENT
PROBLEM TO BE SOLVED: To provide a solid electrolyte body for gas sensor element capable of operating at lower temperature superior in thermal shock resistance at elevated temperature by improving the ion conductivity, and a manufacturing method and a gas sensor using the same.SOLUTION: The solid electrolyte body for gas sensor element constituted of solid electrolyte particles 2 of zirconia which contains a stabilizer has a structure that metal oxide particles 3 are dispersed in solid electrolyte phase M in which many solid electrolyte particles are aggregated. In the solid electrolyte phase, the solid electrolyte particles neighboring to each other have no particle boundary impurity layer between the particle interfaces 21, and the particle interfaces are in direct contact with each other.SELECTED DRAWING: Figure 1
【課題】イオン伝導性をさらに向上させて、より低温で作動可能であり、かつ昇温時の耐熱衝撃性に優れるガスセンサ素子用固体電解質体とその製造方法、それを用いたガスセンサを提供する。【解決手段】安定化剤を含むジルコニアからなる固体電解質粒子２にて構成されるガスセンサ素子用固体電解質体は、上記固体電解質粒子が多数集合した固体電解質相Ｍ中に、金属酸化物粒子３が分散した構造を有しており、上記固体電解質相において、互いに隣り合う２つの上記固体電解質粒子は、それらの粒子界面２１の間に粒界不純物層を有さず、上記粒子界面同士が直接接触している。【選択図】図１
