Investigation of thermally induced processes in corundum refractory concretes with addition of fly ash
(Springer Netherlands, 2015)
The effects that the fly ash addition has on the behavior of thermally resistant corundum concrete were discussed. Experimental program implied production of two refractory composites: "referent" concrete from 20 % of ...
Phase Formation at the Sintering of Sa, Zn, Ti Oxides
(Kiev, 2009)
Complex compounds with oxide phases of Ba, 2n, and 11 are widely used in instrument engineering. It is also important to find such production routes for ceramics, which provide their stable structure and properties. Phase ...
The Influence of Mechanical Activation on Sintering Process of BaCO3-SrCO3-TiO2 System
(Belgrade : Serbian Ceramic Society, 2012)
In this article the influence of mechanical activation on sintering process of barium-strontiumtitanate ceramics has been investigated. Both non-activated and mixtures treated in planetary ball mill for 5, 10, 20, 40, 80 ...
The effect of mechanical activation on synthesis and properties of MgAl2O4 ceramics
(Elsevier, 2019)
Magnesium aluminate, MgAl2O4 and other alumina-based spinels are ceramics with high hardness, high melting point and mechanical strenght. Spinels can also be used as dielectrics in microwave applications. The goal of this ...
Microwave Electro Ceramic Based on Magnesium Titanate Compounds
(Paris : Atlantis Press, 2017)
The intensive progress in electronics, especially telecommunication and mobile phone in 1990s, was the main driving force for the extensive research and development of microwave ceramics. These materials are often used in ...
Mechanically activated coal ash as refractory bauxite shotcrete microfiller: Thermal interactions mechanism investigation
(Elsevier, 2014)
A growing demand for refractory castables with advanced properties has given rise to a continuous technological evolution and highlighted the necessity for secondary raw materials reapplication even in refractory industry. ...
Intrinsic resistivity of sintered Nickel Manganite vs. powder activation time and density
(Belgrade : International Institute for the Science of Sintering, 2008)
In this work the DC resistivity of sintered nickel manganite NiMn2O4 (NTC thermistor material) was studied as a function of additional powder activation time in a planetary ball mill (0, 5, 15, 30, 45 and 60 min). The ...
The influence of mechanical activation on microstructure and dielectric properties of SrTiO3 ceramics
(Belgrade : Innovation Center of Faculty of Mechanical Engineering, 2021)
In recent years, a lot of interest has been shown in obtaining materials with predetermined properties. The aim is to establish a functional dependence between the synthesis parameters, structural characteristics, and ...
Диелектрична керамика баријум‑стронцијум‑титаната / Dielectric Barium Strontium Titanate Ceramics
(Београд : Задужбина Андрејевић, 2021)
С обзиром на то да развој савремене технике није могућ без нових ма‑ теријала, што је објективно последица достигнућа у области науке о материјалима, аутор се у овој монографији бави керамичким материјали‑ ма који већ дуги ...
Synthesis of BaTiO3 from a mechanically activated BaCO 3-TiO2 system
(Belgrade : International Institute for the Science of Sintering, 2008)
In this article the solid state reaction of BaTiO3 formation from a mechanically activated BaCO3-TiO2 system has been investigated. An equimolar mixture of BaCO3 and TiO2 powders was activated in a planetary ball mill in ...
