  3. CIRCOLIT®-Powder

Inspired by the CSH mineral xonotlite (6 CaO x 6 SiO2 x H2O) , which was first discovered in Mexico, its exact crystal structure is synthetically reproduced here.

Again, nature is the very definition of the innovative teacher here.

  • Starting with a very bright whiteness, CIRCOLIT®-Powder contains almost no quartz residue; the abrasion values are very low.
  • Its defined crystal structure and the special grinding technique provide an unusually pronounced rod shape. Additionally CIRCOLIT®-Powder has a high degree of inner porosity as well as the high specific surface.
  • The multifunctional product is used in many various applications.
