This paper discusses the challenges involved in producing high-quality alumina ceramics, particularly when it comes to achieving a suitable degree of surface roughness and high accuracy. Alumina ceramics are widely used in various applications due to their exceptional properties, including high strength, wear resistance and chemical stability. The alumina ceramic pistons with the desired properties and performance were produced from commercially available raw materials. To improve the densification and mechanical properties of the sintered ceramics, an organic binder was used. The use of a diamond abrasive slurry for polishing was also studied, which has proven to be particularly effective in achieving a high degree of surface finish. The study aims to produce alumina-based pistons with a low level of surface roughness as well as discusses the techniques and methods used to achieve this goal. The results of this paper include the porosity, mechanical properties and microstructure of the alumina ceramics produced in addition to the effectiveness of the techniques and methods applied.
