This process enables a compact powder to be sintered to a high density in much shorter sintering time, typically a few minutes, compared with the conventional sintering process. The short sintering time in the SPS process would be advantageous to suppress the chemical reaction between particles, ...
Subsequently, the powder was recovered using a centrifuge (4000 rpm, 5 min), rinsed with distilled water two times to remove residual sodium, and then placed in a drying oven at 80 °C for 24 h. The UC phosphor was synthe-sized with BaMoO4 as a host. The precursor was prepared by ...
The reaction of the barium heated the solution. While the solution was still hot, the strontium was added and allowed to react. When the strontium was all reacted, then the second measure of 2-ethylhexanoic acid was added and, while stirring, the solution was heated to a maximum temperature...
water vapor and ammonia; mixture of powders of monohydrate of barium nitride and titanium oxide is taken in molar ratio [Ba(NO2)2H2O]/TiO2 from 1.0 to 1.3; in reaction space, mole ratio of NH4OH/H2O=1/5; thermal treatment of mixture of reagents with steam containing ammonia is carried ...
[0014] Secondary explosives such as nitrocellulose or pentaerythrite tetranitrate for example are especially suitable as other components that contribute to the reaction. Other examples that could be mentioned are octogen and hexogen, as well as amino compounds of nitrated aromatics, trinitrobenzene fo...
Thin films according to the invention are preferably used as dielectric films of various electronics components. Films according to the invention are deposited, for example, on platinum (Pt), RuO2, IrO2, SrRuO3, LaSrCoO3, IrO2/Ir, RuO2/Pt, silica (SiO2), silicon nitride and silicon surfac...
The luminescence properties of Eu~(2+) -doped barium calcium silicon oxynitrides (general formula: Ba_(4-x)Ca_xSi_6ON_(10): Eu~(2+) (x = 1.8 ~ 2.2)) were examined, together with the preparation conditions for the solid state reaction. Firstly, the stoichiometric amounts of Ba, Ca...
Polycrystalline Ba0.95Bi0.05TiO3 (Bi:BT) ceramics was fabricated by the solid-state reaction technique. High-purity powders of BaCO3, Bi2O3, and TiO2, with purities of 99.99%, 99.97%, and 99.8%, respectively (Sigma-Aldrich, St. Louis, MI, USA), were used as starting materials. In orde...
A cross-section of the sample shows that the crystals are located inside the symmetrical pore channels, which indicates that the reaction is occurring not only on the surface of the sample but also in the volume of the pores. The height of the nanostructured layer after 3 h of treatment is...
