Our Spinel features

The main characteristics of our Spinel products bring optimal transparency with a low scattering loss, without any coloration or defect (black or white spots), and high mechanical properties. Possibility to customize the Spinel chemical composition: Co, Mn, Fe doping, Al/Mg stoichiometry. Often used for ballistic, detection, luxury & catalysis applications. S25CR & S30CR are :

  • Controlled in particle size and size distribution
  • High chemical purity: low sulfur content and low metallic impurities
  • Phase purity
  • Constant crystallographic composition
