Applications in fire resistance, fire protection and foundry materials
CIRCOLIT® and CIRCOSIL® are:
CIRCOLIT® and CIRCOSIL® as synthetic Calcium-Silicate-Hydrates can be used in templates and linings for refractory industry as well as in fire protection panels.
CIRCOSIL® (tobermorite) is available in defined grain bands especially for your use. It is ideal for refractory mortar formulations in fire prevention.
CIRCOLIT®-Powder (Xonotlit) is temperature stable up to 750°C. At high temperatures an endothermic isostructural phase transformation to wollastonite takes place, without changing the crystal structure. Therefore CIRCOLIT® is an indispensable compound in refractory materials.
