We have developed a novel non-firing ceramic process using planetary ball milling with an alkaline hydroxide binding reaction. This can reduce the manufacturing cost (e.g., energy cost), especially during post-forming processing of the desired product. In this study, the surfaces of a raw powder material were mechano-chemically activated using a planetary ball mill, with the addition of a certain amount of alkaline solution that solidified and produced chemical bonding between particles. This was induced to elute cations off of the surface of the particle by milling-assisted activation. In this research paper, the main raw material for the non-firing ceramic product was fabricated using waste sludge from the paper manufacturing industry. The effect of the operational conditions in the planetary ball mill, such as rotational speed and milling time, on the mechanical properties of the solidified body were varied and investigated.
