Abstract
Provided is a method for manufacturing a ceramic formed body enabling the manufacturing of a ceramic formed body having a controlled product shape, such as roundness, by keeping the torque applied to the extrusion machine stable and low, using a forming raw material having well-balanced fluidity and shape-retaining property. A manufacturing method 1 includes: a dry mixing step S1 of dry mixing a raw material 3 by batch processing; a wet mixing step S2 of adding liquid 5 to a dry mixture 4 obtained at the dry mixing step S1 by continuous processing, the liquid including at least one type of water, surfactant, lubricant and plasticizer, while wet mixing; a kneading step S3 of kneading a wet mixture 6 obtained at the wet mixing step S2; and a forming step S4 of extruding a kneaded mixture (forming raw material) obtained at the kneading step S3 to make a ceramic formed body 2.
