96% Undensified Silica Fume is a microsilica with 96% SiO2 content, and the Bulk density is 250-400kg/m³.

Silica fume has been used to improve refractory materials for more than 40 years. Silica fume used in refractory materials will have the following characteristics:

1. Improve the flowability of pouring refractory, reduce water consumption, make it easy to shape, and greatly improve the production efficiency

2. Due to the intercalation effect of its ultrastructure, the compactness and strength of refractories are greatly improved

3. Silica fume has high activity, and under the premise of the presence of Al2O3 components, it is easier to generate Mullite phase, which makes the high-temperature strength and thermal shock of refractory material significantly improved
