U ovom radu su ispitivane strukturne promene BaTiO3 tokom mehaničke aktivacije. Kao početni prah, korišćen je BaTiO3 (Aldrich) prah čistoće 99.9%. Mehanička aktivacija ovog praha izvršena je mlevenjem u visokoenergetskom ...

Adsorption on activated carbon cloth is an efficient procedure for removing pollutants from wastewaters, because this material possesses large specific area and high adsorption capacity. Inthis study the activated carbon ...

Strontium-titanate powder was mechanically activated in a planetary ball mill for 0, 5, 10, 30, 60, 90 and 120 minutes. Non-isothermal sintering of non-activated and activated SrTiO3 powder samples in the temperature ...

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 ...

Mechanical activation is widely used and relatively inexpensive procedure for sintering process sample preparation. However, the influence of pressure, which is used for compaction, has not been completely investigated. ...

Mechanically activated powders (0, 10, 40, 80 and 160 minutes) were formed by isostatic pressure 300 MPa to cylindrical green bodies (φ 12 mm). First set of samples was sintered at 1300°C for 30 min in air (heating rate ...

Cordierite, 2MgO⋅2Al2O3⋅5SiO2, is a very attractive high-temperature ceramic material, due to its outstanding electrical characteristics, such as the low temperature expansion coefficient, low dielectric constant and good ...

Materials based on ZnO structure have more frequently application as fillers in polymer ceramics nanocompozites. Performances of these materials depends on fillers morphology, surfaces texture and particles size. According ...
