MIO – a Rare Mineral

Micaceous Iron Oxides (MIO) are rather scarce, and significant natural resources are known to be available in Europe (Austria), Asia (China), Australia and Africa. There are differences in mineralogy and iron content. The most important quality criteria of MIO products according to EN ISO 10601 are:

  • Content of lamellar particles (minimum 65 % for Grade A,
    EN ISO 10601)
  • Fe2O3 content (min. 85 %)
  • Color of product (grey with metallic sheen)
  • Particle size distribution (PSD)

KMI has a strong focus on Grade A products. Our MIOX® Standard grades AS, SG, DB are designed to meet these requirements.
