Analiza osetljivosti debeloslojnih NTC termistora na promene temperature i protoka vazduha
(Čačak : University of Kragujevac, Faculty of Technical Sciences, 2006)
NTC termistori na bazi Mn, Ni, Co i Fe oksida za potrebe debeloslojnih senzora pripadaju oblasti istraživačkog i primenjenog rada sa ciljem realizacije senzora prilagođenih po obliku, prenosu toplote i brzini odziva fizičkim ...
ZnO varistors prepared by direct mixing of constituent phases
(Sendai : Japan Institute of Metals, 2000)
ZnO varistors with non-linearity coefficients reaching 50 and low values of the leakage current (approximately 0.01 A/m2), were obtained by a method referred to as `direct mixing of constituent phases'. The method is based ...
Densification rate and phase structure changes during sintering of zinc titanate ceramics
Densification rate and phase structure changes during sintering of nanosized ZnTiO3 were studied. Sintering was performed in a dilatometer in two regimes: the first to 900 °C (heating rates 5, 10 and 15 °C/min) and the ...
Thermal diffusivity of sintered 12CaO×7AI2O3
Poster presented at the 14th International Conference on Photoacoustic and Photothermal Phenomena, Cairo, Egypt, January 6-9, 2007
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 ...
Influence of MgO addition on the synthesis and electrical properties of sintered zinc-titanate ceramics
Starting mixtures of ZnO, TiO2 and MgO (0, 1.25 and 2.5 wt.% MgO) powders were mechanically activated for 15 min in a planetary ball mill. The powders obtained were sintered non-isothermally to temperatures between 800 and ...

Science of Sintering in the XXI Century : book of abstracts / X World Round Table Conference on Sintering [3-6 September 2002 Belgrade, Yugoslavia] ; [organized by] Serbian Academy of Sciences and Arts and International ...
Phase Formation at the Sintering of Sa, Zn, Ti Oxides
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 ...
Reduction of the specific surface area of porous ZnO during sintering
(Čačak : Technical Faculty, 2007)
In this paper reduction of the specifice surface area of porous ZnO during sintering was analyzed. ZnO was sintered at temperatures from 673K to 1173K. Reduction of the specific surface area was observed as a function of ...
