GRANULITE® cenospheres are fine free-flowing powder composed of high-strength hollow spherical aluminosilicate particles, and used to reduce costs, and increase the performance of lightweight cements, refractory materials, sound and heat insulation, and other materials to whom less weight with the same structural properties is required in order to reduce the consumption of the expensive components.
Cenosphere are highly stable lightweight additive with high content of Al2O3, as well as low impurities, melting point of 1750°C, and excellent strength-to-density ratio.
We offer a range of grades with different quality characteristics, which are suited to the solution of different process requierments.
a low density 500µ cenosphere suitable for Oil well cement and refractories
500 µ cenosphere with a Mohs scale shell hardness of 6 and a typical crush strength of 3000-6000 psi suitable for the following applications with Al2O3 up to 32-40%, melting point 1750°C and best strength-to-density ratio.
