MATERIAL FOR TEMPERATURE-SENSITIVE RESISTORS WITH POSITIVE TEMPERATURE COEFFICIENT OF RESISTANCE Russian patent published in 1995 - IPC

FIELD: radio electronics. SUBSTANCE: material for temperature-sensitive resistors with positive temperature coefficient of resistance is based on BaTiO₃ with additive YBa₂Cu₃O_7-x(x=0-0,1) (x=0-0.1) with following proportion of components, per cent by mass YBa₂Cu₃O_7-x(x=0-0,1) 0,21-0,86; (x=0-0.1) 0.21-0.86, BaTiO₃ being the balance. EFFECT: expanded temperature interval of positive coefficient of resistance owing to decrease of temperature of start of process, increase of specific volume resistance and decreased temperature of sintering of material. 2 tbl
