Since the discovery of positive temperature coefficient resistive (PTCR) materials, they have
been widely used in electric/electronic thermistor devices for overload protection. The rapid …

Hydroxyapatite (HAP) has been widely used to immobilize many cationic heavy metals in
water and soils. Compared with its strong sorption for metal cations, the abilities of HAP to …

Fe-doped Bi0. 5Na0. 5TiO3 ceramics with Fe-ion content varied from 0 to 0.15 at.% were
successfully prepared by conventional solid state reaction method. The sintering …

The effects of B2O3 vapor doping on the dielectric properties of barium titanate ceramics
were studied. After the doping, the Curie point of BaTiO3 ceramics was increased from 128 …

Earlier studies show that organic and inorganic semiconducting materials are the most
promising materials for use in temperature sensors. In this brief review, attention will be …

The effects of B 2 O 3 addition on the sintering behavior, microstructure and microwave
dielectric properties of the Li 2 CoTi 3 O 8 ceramics were investigated. The variations of …

This work investigated the effect of B 2 O 3 on phase structure and electrical properties of
CuO-modified (Ba 0.95 Ca 0.05)(Ti 0.90 Sn 0.10) O 3–0.5 CuO–xB 2 O 3 (BCTSCu 0.5 B x …

As a promising material for lead-free positive temperature coefficient of resistivity (PTCR)
ceramics,(1− x) BaTiO 3–xK 0.5 Bi 0.5 TiO 3 (x= 0.002–0.008) samples were prepared by …

Nb2O5-doped (1− x) Ba0. 96Ca0. 04TiO3–xBiYO3 (where x= 0.01, 0.02, 0.03 and 0.04) lead-
free PTC thermistor ceramics were prepared by a conventional solid state reaction method …

0.5 wt.% B2O3 doped BaZrxTi1-xO3 ceramics (x= 0, 0.1, 0.2, 0.3, 0.4) were synthesized by
adapting the solid-state synthesis method. B2O3 used as a sintering additive in the BT and …
