AB  - U ovom radu je istraživana mogućnost dobijanja novih vatrostalnih premaza na bazi cirkona koji bi imali primenu u livarstvu. Optimizacija sastava premaza kontrolisana reološkim svojstvima postignuta je primenom različitih komponenata premaza, naročito primenom novog veziva na bazi suspenzije i variranjem načina spravljanja premaza. Čestice cirkonskoh praha veličine 25×10-6 m su korišćene kao ispuna. Uzorak cirkona ispitivan je pomoću sledećih metoda: difrakcija X-zraka, diferencijalna termalna analiza i mikroskopija. Oblik i veličina zrna su analizirani pomoću računarskog programa za analizu slike OZARIA 2.5. Pokazano je da primena ovih premaza na bazi vode i alkohola ima pozitivan uticaj na kvalitet površine, tj. na strukturne i mehaničke karakteristike odlivaka livenog gvožđa koji su dobijeni metodom livenja u peščane kalupe i pomoću isparljivih modela (Lost Foam metoda livenja).
AB  - In this work, a possibility to develop a new zircon-based refractory coating for casting applications was investigated. Optimization of the coating composition with controlled rheological properties was attained by application of different coating components, particularly by application of a new suspension agent and by alteration of coating production procedure. Zircon powder with particle size of 25×10-6 m was used as filler. The zircon sample was investigated by means of X-ray diffraction analysis, diffraction thermal analysis and polarized microscopy. The shape and grain size were analyzed using OZARIA 2.5 software. It was shown that application of this type of water-alcohol-based coating had a positive influence on surface quality, structural and mechanical properties of the castings of cast iron obtained by pouring into sand molds by means of the expandable patterns method (Lost Foam casting process).

AB  - This paper presents the results of research on mechanical activation of raw talc in a high-energy speed rotary mechanoactivator. The results of research on effect of mechanically activated talc on the degree of recovery Fe2O3 by hydrometallurgical method are also presented. The process and mechanism of mechanical activation in this type of mechanoactivator were achieved by impact. The variable parameters of the inechanoactivator operation were: rate of rotor revolutions (n(0) = 10,000 and n(0) = 20,000 rpm), circle sieve mesh (80, 120, 200 and 500 mu m) and the current intensity. The following parameters of the dry mechanical activation process were studied: mechanical activation time, rotor speed, mechanoactivator capacity and specific energy consumption. The mechanically activated powder was examined by application of differential thermal and thermogravimetric analyses, analysis of the degree of mechanical activation and the specific surface area as well. According to the obtained results, the highest rate of mechanical activation was obtained with a nominal mechanoactivator load. The degree of mechanical activation increases with increasing the rate of rotor revolution, circle sieve mesh size and with the increasing mechanoactivator load. It was shown that high-grade talc concentrate with low content of Fe2O3 can be obtained by physical-chemical process. A new approach for obtaining high-grade talc concentrate was achieved trough mechanically activated talc effect on the degree of recovery of Fe2O3 by hydrometallurgical process.

AB  - Standard raw materials, kaolin, talc, MgO, alumina, feldspar and sepiolite, were used in synthesis of four different cordierite type ceramics. Sintered cordierite was used as refractory filler in the ceramic coating for evaporative polystyrene patterns in the EPC process. The cordierite samples were tested by the following methods: roentgen diffraction analysis, diffraction thermal analysis and polarized microscope. The shape and grain size were analyzed by the program package OZARIA 2.5. In order to evaluate the possible application of cordierite as the refractory filler, four different coating processes were investigated.
