Tohoku University Technology: Slurry and spherical particle production method: T20-505
Production of small size and dense spherical particle by cancelling slurry precipitation Possible to apply to MoSiBTiC alloy particle
Particles with a uniform size of few 10 to 100 ㎛ are expected to be used as raw material for additive manufacturing (3D printer). The Pulsated Orifice Ejection Method (POEM) and the freeze-dry POEM (FD-POEM) developed by the inventor are used for their production. From the point of view of composition control and spheronization by surface tension, the raw material is preferable to be in slurry form. However, the precipitation in a short time and consequently high particle concentration cannot be achieved. This invention makes possible to disperse particle for a relatively long time at a high concentration and to produce small & dense spherical particle than the conventional one using FD-POEM. Moreover, this invention can be applied to particle production of MoSiBTiC alloy, which is an ultra-high temperature material.

Company information
The revenue generated from technology transfer is reinvested as new research funding for universities and researchers, and is utilized to create further research outcomes. To ensure the smooth operation of this cycle, known as the "Intellectual Creation Cycle," we will vigorously promote technology transfer. The types of seeds we handle include patents, know-how, databases, and programs. We have established a collaborative framework by signing basic technology transfer agreements with the following universities (as of June 1, 2025): Tohoku University, Hirosaki University, Iwate University, Akita University, Fukushima University, Yamagata University, Tohoku Gakuin University, Iwate Medical University, Fukushima Medical University, Aizu University, Miyagi University, Hokkaido University, Muroran Institute of Technology, and Showa Medical University.
