Abstract
The present invention relates to a slurry containing water, amorphous silica particles having a particle size less than 1 μm and silica flour with a particle size between 2-200 μm. In order to stabilize the slurry, the slurry contains a polysaccharide. The invention further relates to a method for the production of a slurry containing water, amorphous silica having a particle size below 1 μm, and silica flour with a particle size between 2-200 μm, where a polysaccharide is added to a slurry of water and amorphous silica, whereafter the silica flour is mixed into the slurry of amorphous silica.
