Studying 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...

Effect 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...

Population change in the fine structure levels of cesium atoms using chirped laser

Here, the population transfer between two specific levels of Cesium atomunder the influence of chirped laser source has been numerically investigated. The maingoal of this study is the engineering of the population transfer between the 62S1/2 and 62P1/2levels of Cesium which is corresponding to its D1 transition line using a chirped lasersource. Constructing the system Hamiltonian, as well as t...

The 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...
