abstract = "Ispitana je mogućnost primene metil metakrilata, MMA, kao akrilnog veziva u pripremi keramičkog praha alumine za presovanje sa namerom da se poboljša mašinska obradljivost ispresaka od alumine. Poređene su osobine ispresaka i osobine njima odgovarajućih sinterovanih uzoraka koji su pripremljeni sa i bez akrilnog veziva. Visoka gustina ispresaka sa MMA (2,35 g/cm3) u odnosu na ispreske samo od alumine (2,11 g/cm3) formiranih pod optimalnim pritiskom presovanja od 60 MPa, ukazuje na uticaj akrilata na poboljšano pakovanje praha alumine i njihovu odličnu mašinsku obradljivost; kod sinterovanih uzoraka povećana je poroznost, a smanjene su gustina i procenat linearnog skupljanja. Pokazano je da se mašinskom obradom ispresaka alumine sa MMA, mogu napraviti složene forme poput keramičkog zavrtnja ili keramički delovi sklopova, sa velikim mogućnostima komercijalne primene., Investigated the possibility of using methyl methacrylate (MMA) as an acrylic binder in the preparation of ceramic powder of alumina for pressing with the intention of improving machinability of alumina flakes. Compared the properties of the green bodies and the properties of their corresponding sintered samples that are prepared with and without acrylic binder. The achieved higher density of green bodies with MMA (2.35 g/cm3) compared to green bodies without MMA (2.11 g/cm3) were formed under the optimal pressure of 60 MPa, indicating the improved packing of alumina powder with addition of acrylate. In the case of sintered samples, the porosities were increased, and the density and percentage of linear shrinkage were reduced. It has been shown that machining of green bodies, prepared with MMA, can be produced in the form of complex ceramic products of alumina like a screw with a nut and with great possibilities of commercial application.",
