Characterization and radionuclides contents of diatomaceous earth from Kolubara mining basin, Serbia
(Univeristy of Belgrade, Faculty of Mining and Geology, Belgrade, Serbia, 2019)
Diatomaceous earth is of sedimentary origin consists mainly of accumulated skeletons formed as a protective covering of the diatoms. Usually, high absorption capacity of diatomaceous earth provides its wide use as heat ...
The influence of hydrochloric acid on the features of SBA-15 particles
(Society of Physical Chemists of Serbia, 2021)
The template method synthesis of both SBA-15 materials with elongated and spherical particles was performed using a surfactant Pluronic P123. The HCl (p.a.) was used to synthesize material with elongated particles connected ...
Characterization of diatomaceous earth from Kolubara mining basin, Serbia
(Serbian Ceramic Society, 2019)
Diatomaceous earth is of sedimentary origin consists mainly of accumulated skeletons formed as a protective covering of the diatoms. Usually, high absorption capacity of diatomaceous earth provides its wide use as heat ...
Characterization of clay from Kolubara mining basin, Serbia
(Serbian Ceramic Society, 2019)
During coal exploitation in the Kolubara mining basin, Serbia, clay is deposited as accompanying mineral. The aim of the present study is to analyze the activity concentrations of terrestrial (226Ra, 232Th and 40K) and ...
Synthesis of spherical SBA-15 silica particles without the use of additional cosurfactant
(Serbian Ceramic Society, 2021)
The synthesis of SBA-15 material with spherical particles is performed by the template method by using only a surfactant Pluronic P123 under acidic conditions. In the synthesis of SBA-15 with spherical particles, an HCl ...
Composition and natural radionuclides in clay from Kolubara mining basin, Serbia
(Univeristy of Belgrade, Faculty of Mining and Geology, Belgrade, Serbia, 2019)
The mining basin Kolubara lies about 50 km southwest of Belgrade and stretches across the river Kolubara from Lajkovac to its mouth in the Sava River. During coal exploitation a huge amount of clay is deposited ...
Characterization of clay mineral from Kolubara mining basin, Serbia, with a determined layered structure
(Serbian Ceramic Society, 2021)
The clay minerals deposit from the mining basin Kolubara, Serbia, is a natural sediment material with high economic potential in many fields. The chemical composition of starting clay determined by inductively coupled ...
Preparation and dielectric properties of CuAlO2 ceramics
(48th International Conference on Microelectronics, Devices and Materials with the Workshop on Ceramic Microsystems, 2012)
Within this work, the focus was on preparation of the delafossite CuAlO2 single phase powder and ceramic with a high density by the solid state synthesis, and on dielectric properties of the as-synthesized ceramic. The ...
Self-sustained combustion synthesis of the p-type nanocrystalline CuAlO2 powder
(Ljubljana : Jožef Stefan Institute, 2013, 2013)
Recently, a considerable effort has been devoted to research and improvement of both dielectrics and wide band-gap semiconductors for the realization of fully transparent devices. Due to the lack of available p-type ...
Processing-property relationship for solid-state synthesized CuAlO2 ceramic
(Conference of the European Ceramic Society XIV, Toledo, 2015)
Copper aluminate (CuAlO2) is the most extensively studied cuprous delafossite (general formula: A+B3+O2, group: R-3m) p-type semiconductor, whose exceptional electrical, optical, magnetic and catalytic properties found ...
