The influence of mechanical activation on sintering process of BaCO3-SrCO3-TiO2 system
(Belgrade : International Institute for the Science of Sintering, 2012)
In this article the influence of mechanical activation on sintering process of bariumstrontium-titanate ceramics has been investigated. Both non-activated and mixtures treated in a planetary ball mill for 5, 10, 20, 40, ...
Shungite – a carbon-mineral rock material: Its sinterability and possible applications
(Novi Sad : Faculty of Technology, University of Novi Sad, 2019)
The paper presents results of the influence of mechanical activation of shungite, a carbon-mineral rock material rich in silica and carbon, on its sintering behaviour, and obtaining of pure SiC ceramics. The mechanical ...
Physical Properties of Sintered Alumina Doped with Different Oxides
(Belgrade : ETRAN, 2018)
Corundum (α-alumina) is a suitable material for usage in various industry fields owing to its chemical stability, electrical and mechanical features. It is known that properties of ceramics could be modified by addition ...
Structural investigation of mechanically activated ZnO powder
(Elsevier, 2015)
Abstract Commercially available ZnO powder was mechanically activated in a planetary ball mill. In order to investigate the specific surface area, pore volume and microstructure of non-activated and mechanically activated ...
The Morphological Characterization of Mechanically Activated ZnO Powder
(Belgrade : Serbian Ceramic Society, 2014)
The authors investigated the morphological characteristics of mechanically activated ZnO powder. ZnO powder was mechanically activated for 2, 5, 10 and 30 minutes in a planetary ball mill. Mechanical activation introduces ...
Synthesis and characterization of zinc titanate nano-crystal powders obtained by mechanical activation
(Belgrade : International Institute for the Science of Sintering, 2005)
Development of dielectric materials for microwave frequencies is increasing with rapid progress in mobile and satellite communications systems, where zinc titanates have found application due to their semi-conducting and ...
The impedance analysis of sintered MgTiO3 ceramics
(Elsevier, 2017)
In the present study the effect of preparation conditions on microstructure and electrical properties of MgTiO3 ceramics was investigated. Mixture of MgO and TiO2 powders was subjected to mechanical activation for different ...
Electrical Properties of Sintered Magnesium- titanate Ceramics
(Belgrade : Serbian Ceramic Society, 2012)
Mixtures of MgO and TiO2 were mechanically activated in a planetary ball mill for different time intervals. Thus obtained powders were sintered in a furnace for 2 h at temperature of 1300 °C in air atmosphere. Raman ...
Influence of prolonged sintering time on density and electrical properties of isothermally sintered cordierite-based ceramics
(Belgrade : International Institute for the Science of Sintering, 2013)
Mechanical activation is a commonly used and relatively fast and inexpensive procedure for sample preparation before the sintering process. Cordierite, a stoichiometric mixture of three different oxides (2MgO⋅2Al2O3⋅5SiO2) ...
Electrical properties of isothermally sintered cordierite-based ceramics as function of sintering and activation time / Električna svojstva izotermski sinterovane keramike na bazi kordierita kao funkcija vremena sinterovanja i aktivacije
(Beograd : Savez mašinskih i elektrotehničkih inženjera i tehničara Srbije - SMEITS, 2021)
The mechanical activation of the starting mixtures of cordierite (2MgO*2Al2O3*5SiO2) with 5.00 mass % TiO2 was performed in a high energy ball mill during 10-80 min. The applied compaction pressure before the sintering ...
