15 صفحه اولStudying the Effects of Nano Sintering Additives on Microstructure and Electrical Properties of Potassium-Sodium Niobate Piezoceramics
In this paper, lead free (K0.48,Na0.52)NbO3 (KNN(48-52)) piezoelectric ceramics were made by conventional solid state sintering process. Additives of nano ZnO (n-ZnO), nano CuO (n-CuO) and nano SnO2 (n-SnO2) were used in order to decrease the sintering temperature, as well as modifying the dielectric, piezoelectric and ferroelectric propert...
متن کاملEffect of nano and micron WO3 on microstructure and electrical properties of lead free potassium sodium niobate piezoceramics
Lead free potassium sodium niobate (KNN) piezoceramics were synthesized via conventional solid state sintering route. Nano and micron WO3 were separately added to KNN through ball-milling. Dielectric and piezoelectric properties of samples sintered in the temperature range of 1110°-1145°C were measured by precision LCR-meter and APC d33-meter devices. The results revealed that micron WO3 partic...
متن کاملEnvironmental Friendly Potassium Sodium Niobate Based Thin Films from Solutions
We present the synthesis of ~250 nm thick K0.5Na0.5NbO3 thin films on platinized silicon substrates from alkoxide-based solutions with the stoichiometric composition and with the 5 or 10 mole % potassium acetate excess. The films crystallized into a pure perovskite phase, but depending on the amount of the alkali excess in solutions, they consisted of ~50 nm or of ~200 nm large grains. The fine...
متن کاملThe effect of titanium dioxide and molybdenum oxide on the properties of sodium potassium niobate piezoceramic
Sodium potassium niobate piezoceramics are considered as lead-free piezoelectric due to their good properties. In this study, the effect of titanium dioxide and molybdenum oxide as dopant on the densification behavior, piezoelectric and dielectric properties of lithium doped sodium potassium niobate ((K0.5Na0.5)0.94Li0.06NbO3, KNNL) was investigated. For this purpose, (K0.5Na0.5)0.94Li0.06Nb0.9...
