(6 CaO x 6 SiO2 x H2O)CIRCOLIT®-Powder is a synthetic CalciumSilicateHydrate in the crystal form xonotlite
and as a free-flowing white powder easily dispersible in organic and mineral solvents.
CIRCOLIT®-Powder is multifunctional. It is rod-shaped and thus strengthens microscopically.
The material is highly porous when in slightly dispersed condition and thus transfers this condition to the finished systems.
CIRCOLIT®-Powder is temperature-stable up to approx.750 °C. At high temperatures an endothermic isostructural phase transformation to wallastonite takes place, without changing the crystal structure.
