Business Development Area

In the development of new strategic products and new technologies, we promote innovation by consistently managing everything from business planning to basic/practical research, commercial production, and follow-up of commercial production.


Unlike naturally occurring mica, synthetic mica is manufactured from high-purity raw materials, so it is safe, has no dullness in color, and can be used at high temperatures. It is used in a wide range of fields for pulverization, surface treatment, dispersion, etc.
