- Alkali silicates in granular form with higher bulk densities can according to the teaching of European patent application EP-A-0 526 978, whereby an alkali silicate solution with a solids content between 30 and introduces 53% by weight into a heated drum, one in the longitudinal axis Shaft with a variety of close to the inner surface of the drum Arms rotates, the drum wall having a temperature between 150 and 200 ° C and the drying process by a fed into the drum Supported gas with a temperature between 175 and about 250 ° C becomes. According to this process, a product is obtained, the middle one Particle size is in the range between 0.2 and 2 mm. A preferred one Drying gas is heated air.
- European patent application EP-A-0 542 131 describes a process in which a product which is completely soluble in water at room temperature and has a bulk density of between 500 and 1200 g / l is obtained. Drying is preferably carried out using heated air.

- the unpublished international patent application WO 95/33684 also describes a water-soluble, amorphous and granular alkali silicate, which is similar to that described in EP-A-0 526 978 is produced, but contains silicic acid.
- amorphous is meant "X-ray amorphous”. This means that the alkali silicates at X-ray diffraction images do not provide sharp reflections, but at most one or more broad maxima, the width of which is several degree units of the diffraction angle is. However, this does not mean that in electron diffraction experiments areas are found that are sharp Provide electron diffraction reflections. This is to be interpreted as meaning that Substance microcrystalline areas in the order of magnitude up to approx. 20 nm (max. 50 nm).
