Processing-Dependent Broadband Dielectric Properties of KTaO3 Ceramics, Films and KTa0.6Nb0.4O3 Films
KTaO3 belongs to the group of incipient ferroelectrics, which are materials important from the fundamental, as well as from the applications, point of view. It is well known in its single-crystal form; however, the processing of technologically interesting ceramics and thin films is a challenging task and knowledge of their …
A New Synthesis Route to Pb(Mg1/3Nb2/3)O3-Based Materials by the Controlled Agglomeration of Reagent Particles
In this thesis we demonstrate a new, simple, and ecient method for the solid-state synthesis of oxides with a complex chemical composition. We modify the traditional solidstate synthesis method, which is used in the majority of ceramics laboratories around the world, in order to prepare multi-metallic oxide powders from classic …
Hydraulic load cells for measurement of small loads
This work deals with the design of a small kitchen appliance with a weighing function integrated into a control loop in order to prevent unbalanced movement of the appliance during operation. In this particular case, the weighing should be appropriate for larger amounts (up to 5 kg) of ingredients. The …
Structural and electrical properties of 0.65PMN-0.35PT thick films on different substrates
A starting powder with the nominal composition 0.65Pb(Mg1/3Nb2/3)O3–0.35PbTiO3 (0.65PMN–0.35PT), which corresponds to the morphotropic phase boundary (MPB) composition, was prepared by mechanochemical activation followed by attritor milling and low-temperature calcination at 700°C. It had a narrow particle size distribution with the median particle size equal to 0.3 μm. From the …
High-alumina porcelain with improved mechanical and thermal properties
The study presents the influence of increasing the amount of β-spodumene (LiAlSi2O6) as Li2O-content flux on phase composition, microstructural evolution and physical properties of high alumina porcelain material containing ~61% of Al2O3. New porcelain compositions based on clays and high amount of calcined alumina were developed with the introduction of …
