             abstract = "Advanced ceramic materials constitute a mature technology with a 
                         very broad base of current and potential applications and a 
                         growing list of material compositions. Within the advanced 
                         ceramics category, silicon nitride based ceramics are 
                         wear-resistant, corrosion- resistant and lightweight materials, 
                         and are superior to many materials with regard to stability in 
                         high-temperature environments. Because of this combination the 
                         silicon nitride ceramics have an especially high potential to 
                         resolve a wide number of machining problems in the industries. 
                         Presently the Si3N4 ceramic cutting tool inserts are developed 
                         using additives powders that are pressed and sintered in the form 
                         of a cutting tool insert at a temperature of 1850 oC using 
                         pressureless sintering. The microstructure of the material was 
                         observed and analyzed using XRD, SEM, and the mechanical response 
                         of this array microstructure was characterized for hardness 
                         Vickers and fracture toughness. The results show that Si3N4/20 
                         wt.% (AlN and Y2O3) gives the best balance between hardness 
                         Vickers and fracture toughness. The Si3N4/15 wt.% (AlN and Y2O3) 
                         composition allows the production of a very fine-grained 
                         microstructure with low decreasing of the fracture toughness and 
                         increased hardness Vickers. These ceramic cutting tools present 
                         adequate characteristics for future application on dry 
                         machining.",
