Structural characterization of mechanically activated MgO-TiO2 system
(Belgrade : Serbian Ceramic Society, 2013)
In this article the influence of ball miling process on structure of MgO-TiO2 system was investigated. The mixtures of MgO-TiO2 powders were mechanically activated in a planetary ball mill for the time period from 0 to 120 ...
Characterization of mechanically activated ZnO powder
(Belgrade : Serbian Ceramic Society, 2013)
Materials based on ZnO structure have more frequently application as fillers in polymer ceramics nanocompozites. Performances of these materials depends on fillers morphology, surfaces texture and particles size. According ...
Two-step sintering, phase transformations, electrical and mechanical properties of nanostructured bioceramic materials based on hydroxyapatite
(Belgrade : Materials Research Society of Serbia, 2013)
Hydroxyapatite based materials are still the most promising materials in the field of skeletal and dental tissue reconstruction. Improvement of their existing properties and broadening their application fields requires ...
Dilatometric Analysis of Mechanically Activated SrTiO3 Powder
(Belgrade : Serbian Ceramic Society, 2013)
Strontium-titanate powder was mechanically activated in a planetary ball mill for 0, 5, 10, 30, 60, 90 and 120 minutes. Non-isothermal sintering of non-activated and activated SrTiO3 powder samples in the temperature ...
Lightweight construction ceramic composites based of pelletized fly ash aggregate
(Belgrade : Serbian Ceramic Society, 2013)
As coal combustion byproduct fly ash represents a risk for environment: direct ash emission from open land-fills causes pollution of air, soil and water. The solution for this severe pollution problem is fly ash reapplication ...
Preparation and characterization of Cu and Zn modified nickel manganite NTC powders and thick film thermistors
(Elsevier, 2013)
A simple ball milling/thermal treatment procedure was applied to obtain fine thermistor powders. Three different powder compositions were analyzed–Cu0.2Ni0.5Zn1.0Mn1.3O4, Cu0.25Ni0.5Zn1.0Mn1.25O4 and Cu0.4Ni0.5Mn2.1O4. XRD ...
Application of Minkowski layer for microalloyed alumo-silicate ceramics grains fractal analysis
(Belgrade : Serbian Ceramic Society, 2013)
Porous aluminium-silicate ceramics, modified by alloying with magnesium and microalloying with alluminium belongs to a group of advanced multifunctional ceramics materials. This multiphase solid-solid system has predominantly ...
Aerosol route as a feasible bottom-up chemical approach for up-converting phosphor particles processing
(Elsevier, 2013)
The opportunities of the hot wall aerosol synthesis, i.e. conventional spray pyrolysis (CSP) method are demonstrated for the generation of highly spherical three-dimensional (3D) nanostructured phosphor particles with ...
Primena senzora tipa Kinect u snimanju trajektorija zglobova šake
(Beograd : Društvo za ETRAN, 2013)
Rad prikazuje jedan pristup u merenju 3D pozicija karakterističnih zglobova ljudske šake korišćenjem senzora tipa Kinect, kao jeftine alternative skupim vizuelnim sistemima. Navedene su osnovne karakteristike ovog senzora ...
Uniaxial tension of drying sieves / Jednoosno zatezanje sušnih sita
(Belgrade : Association of the Chemical Engineers of Serbia, 2013)
Although the literature contains numerous studies that have been developed to describe the nonlinear behavior of drying sieves' operation, there are no papers in this which report deeper investigation of the drying sieve ...
