With the development of electronic information, automatic control, home
appliances and transportation and other fields. BaTi O_3-based PTC ceramics
have been widely used as one of the important application fields of
ferroelectric ceramics, and the market demand is increasing day by day. Aiming
at the current vacancy of low room temperature resistivity and low temperature
coefficient of temperature coefficient of positive temperature coefficient. The
company has studied BaTiO_3-based PTC ceramics for compensating negative
temperature coefficient components. In this paper, BaTiO_3 based
thermosensitive ceramics (with the addition of Sr as the peak shifting agent at
40mol%) were prepared by solid-phase method. The effects of synthesis
temperature, sintering temperature, acceptor doping, donor doping, barium-
titanium ratio, and AST on the microstructure and electrical properties of the
samples were studied. Through process and formulation optimization, a PTC
thermosensitive material for low-resistance temperature compensation with a
resistivity at room temperature of 590Ω? Cm and a temperature coefficient of
resistance in the range of -20 ° C to 80 ° C ranging from 2.11% to 2.72% was
prepared. In this paper, the effects of synthesis temperature and sintering
temperature on the properties of BaTi O_3 based ceramics were first studied.
The experimental results show that when the synthetic firing temperature is
1150 ° C and the sintering temperature is 1340 ° C, the sample grain size
distribution is uniform, the ceramic body has a high density, the room
temperature resistivity is the lowest, the resistance temperature coefficient
is small, and the resistance temperature characteristic curve is highly linear
. Based on the optimal sintering system, this paper studies the effect of the
acceptor additive Mn (NO_3) _2, which is commonly used in ceramic PTC
materials, on the properties of BaTiO_3-based ceramics. The experimental
results show that as the acceptor content increases, the room temperature of
the sample Resistivity and temperature coefficient of resistance increased
significantly. Based on the target performance of this topic, the performance
of samples without acceptor ion is better. On the basis of the above
experiments, the effects of donor Y_2O_3 and Nb_2O_5 doping on the properties
of BaTi O_3 based ceramics were studied.
