High temperature anomaly of electrical conduction in In2O3–SrO ceramics

Abstract: Дослiджено зниження електропровiдности керамiки In2O3-SrO з температурою в дiяпазонi 560-670 K в повiтрi. При кiмнатнiй температурi такiй керамiцi властива нелiнiйна залежнiсть струму вiд напруги з дiлянкою обмеження струму. Виконано термографiчнi дослiдження, рентґенiвську фотоелектронну спектроскопiю, електронну мiкроскопiю та вивчено температурну залежнiсть електропровiдности оксидно-iндiєвого матерiялу в повiтрi, аргонi та сумiшi аргону з киснем. На основi одержаних експериментальних результатiв, зниження … Show more

“…Oxide ceramics is well known as a material for the preparation of surface acoustic wave devices [1], superconductors [2], current limiters [3], catalysts [4], gas sensors [5], humidity sensors [6][7][8][9][10][11], varistors [12][13][14][15][16][17][18][19] etc. The tin oxide based ceramics has many low electrical resistance grains which are usually separated by the layers with high electrical resistance.…”
