Spray drying is mainly use for manufacturing ceramic powders for many applications. In this study granulated and sintered chromium oxide powders were characterised. Powders were manufactured via spray-drying and sintering method, giving special attention to the slurry preparation. After granulation the powders were sintered in Ar-6H2 atmosphere at three different temperatures. The morphology and cross section of the powders were analysed with scanning electron microscopy (SEM) to study grain growth and density. The particle sizes were measured with laser diffractometer and the mechanical strength with an axial pressure test. The effect of slurry preparation, granulation and sintering conditions to density, particle size, mechanical strength and grain growth are presented.
