Enhancement of titanate nanotubes dispersion for reinforcement of nylon-II nanocomposites
(Las Vegas, 2013)
The purpose of the present study was to investigate the effect of titanate nanotubes (TINTs) dispersion in the mechanical properties of Nylon 11 (polyamide 11) polymer. According ,to the existing literature small amounts ...
Density of the ZnTiO3 nanopowder as a loose powder and as a compact obtained by different methods
(Belgrade : Serbian Ceramic Society, 2013)
Nanopowder density, as well as compact density, is due to powder particle size, different in their values, compared to micron powders. Also, the technique used for density determination induces large mutual value discrepancies. ...
Functionalization of the titanate nanotubes with a silane coupling agent
(Belgrade : Institute for Multidisciplinary Research, 2013)
In order to develop new nanosized filler compatible with the thermoplastic polymer Nyion-11, trititanate nanotubes (TTNTs) were synthesized by standard alkaline hydrothermal treatment of a TiO2 anatase powder in 10 M NaOH ...
The influence of mechanical activation on the electrical properties of Ba0.77Sr0.23TiO3 ceramics
(Belgrade : Serbian Ceramic Society, 2013)
Ferroelectric ceramic barium strontium titanate (Ba0.77Sr0.23TiO3), BST, was prepared by solid-state reactions using starting powders of barium carbonate (BaCO3), strontium carbonate (SrCO3) and titanium dioxide (TiO2-anatase). ...
CaCu3Ru4O12/CaCu3Ti4O12/CaCu3Ru4O12 functionally graded electronic ceramics
(Belgrade : Materials Research Society of Serbia, 2013)
Materials exhibiting a high dielectric constant with low sensitivity to temperature variation have great technological significance. Recently, the colossal permittivity of ~104-105 in the kilohertz region at room temperature, ...
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 ...
