Details

Micro-silica fume, also known as silica fume, in the high temperature of 2000 degrees under the oxidation of the formation. Ultrafine high purity amorphous silica, observed under electron microscopy its shape is spherical, amorphous amorphous, the average particle size of 0.2 microns. Has excellent physical and chemical properties.

Micro-silica fume for the improvement of refractory materials have been more than 40 years of history, micro-silica fume for refractory materials will have the following characteristics:


1. To improve the flow of refractory castable, reduce water consumption, making it easy to shape, greatly improve the production efficiency;

2. Due to its ultrafine structure of the interstitial effect, the compactness and strength of refractory material has been greatly improved;

3. Micro-silica fume with high activity, in the presence of Al 2 O 3 composition, the more easy to produce mullite phase, so that refractory high temperature strength, thermal shock significantly improved.
