Characterization of pressure-less sintered MgO-Al2O3-SiO2-TeO2 system
(Belgrade : Materials Research Society of Serbia, 2017)
In this study, sintering of two systems was investigated in parallel, pure cordierite 2MgO:2Al2O3:5SiO2, and cordierite with addition of 5 mass % TeO2. Green bodies were prepared from powder mixtures mechanically activated ...
Reaction kinetics of mechanically activated cordierite based ceramics studied via DTA
(Ljubljana : Central and Eastern European Committee for Thermal Analysis and Calorimetry, 2015)
Cordierite, 2MgO•2Ah03•5Si02 (MAS), is a very attractive high-temperature ceramic material. In order to accelerate the process of sintering, 5.00 mass% Mo03 was added to the starting mixtures. The mechanical activation of ...
Artificial fly ash based aggregates properties influence on lightweight concrete performances
(Elsevier, 2015)
The effect of the application of pelletized fly ash based aggregates obtained through different processing techniques on the behavior of lightweight concretes was analyzed. Experimental program implied production of four ...
Sintering of mechanically activated Zno-TiO 2 powders
(Springer, 2008)
Zinc oxide and titanium dioxide powders mixed in an equimolar ratio are mechanically activated in a planetary ball mill and sintered under nonisothermal and isothermal conditions. Nonisothermal sintering is studied using ...
Electret state in Bi4Ti3O12 ceramics
(Elsevier, 2010)
The effect of thermal treatment atmosphere (argon, air or oxygen) on the electret behavior of bismuth titanate (Bi4Ti3O12) ceramics was investigated. Polycrystalline ferroelectric ceramics were prepared by reactive liquid ...
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 ...
Sintering of defect-free functionally graded biomaterials
(Belgrade : Materials Research Society of Serbia, 2011)
Functionally graded materials (FGMs) with a gradient of chemical, electrical, mechanical and/or biological properties are very attractive because of their superior features compared to conventional materials. It is known ...
Molecular design of nanoparticles and functional materials by sintering
(Beograd : Tehnološko-metalurški fakultet Univerziteta u Beogradu, 2012)
Nanosized powders present an excellent starting point for the formation of nonporous materials during the sintering process. Narrow particle size distributions and sufficiently small sizes of the precursor powders typically ...
Sintering effects on microstructure and dielectric properties of CCTO ceramics
(Belgrade : Materials Research Society of Serbia, 2012)
A perovskite-type compound, calcium copper titanate (CaCu3Ti4O12, CCTO) attracted ever increasing attention for its practical applications in microelectronics, especially for preparation of capacitors and memory devices. ...
Structural analysis of Zn2TiO4 doped with MgO
(Springer, 2009)
The starting mixtures of ZnO, TiO2, and MgO (0, 1.25, and 2.5 wt.%) powders are mechanically activated in a high-energy planetary mill for 15 min and then sintered between 800 and 1100°C for 2 h. The influence of MgO ...
