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 ...
Structural and electrical properties of Ti doped α-Fe2O3
(Belgrade : International Institute for the Science of Sintering, 2013)
In this work we have analyzed the effects of Ti doping on structural and electrical properties of α-Fe2O3. When the amount of added Ti (5 wt.%TiO2) was within the solubility degree and XRD, SEM and EDS analysis revealed a ...
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) ...
Sintering of the mechanically activated MgO-TiO2 system
(Hanyang University Press, 2013)
Mixtures of MgO-TiO2 powders were mechanically activated in a planetary ball mill for a time interval from 0 to 120 minutes. The influence of the mechanical activation on the phase composition and crystal structure have ...
