Product Information

Powder of high purity homogenous aluminium silicon carbide (spinel), TATEMIC® produced by Tateho Chemical


Spinel Material

High purity homogeneous magnesium aluminate (Spinel)



Tateho has developed the TATEMIC® homogeneous spinel material by using special refining technology.
According to your request, Tateho can customize various physical properties (particle diameter, thermal expansion coefficient etc.).
So TATEMIC® can be widely used for various purposes including applications of fine ceramic materials.

Spinel Materials with Customized Coefficient of Thermal Expansion

1. High Purity Homogeneous Composition

- TATEMIC® has very high spinel purity and hardly contains Al2O3.

2. Customizing Particle Size

- Tateho can customize its particle size from submicron (excellent in dispersibility in solution) to several tens microns (excellent in fluidity during powder filling).

3. Customizing Coefficient of Thermal Expansion

- Tateho can customize coefficient of thermal expansion of TATEMIC® arbitrarily.
