 · Colloidal Silica Sol the high-purity silica sol refers to a silica sol having a low metal content, a high uniform distribution, and good stability. Colloidal silica sol is mainly used in the semiconductor polishing industry, but also in catalyst carriers, coatings, cosmetics, food clarifiers and other industries. ZXCHEM GROUP

Colloidal silica. We produce colloidal dispersions of silica particles in water under the trade name Köstrosol ®. The particles are made from high-purity alkali silicate. They are spherical and generally non-crosslinked and are hydroxylated at the surface. The reactivity of our colloidal silica can be modified and changed according to their ...

 · Colloidal silica is non-ionic, and is typically found in surface waters. It creates problems in water treatment because of its stability as an un-ionized compound, which makes it difficult to remove using ion exchange processes. It can even cause some resin fouling where colloidal silica levels are exceedingly ...

 · Colloidal silica is a liquid dispersion of silicon dioxide, the same material found naturally in sand. Like other colloids, it consists of microscopic particles evenly dispersed throughout a different substance — in this case, a solid dispersed in a liquid. This mixture is known as a sol, and it has numerous industrial and commercial ...

Packing & Storage. Using 25 kg, 250 kg Plastic drums, 1000 kg IBC or TANK, Flexibag. Storage should avoid exposure and freezing, avoid exposure to long-term contact with air. The containers used, should be washed as soon as possible with water so as to avoid silica deposition. If there is a deposition of colloidal sol in drum pls rinse with 10% ...

 · Colloidal silica hasn't always been the versatile problem solver that it is today. In fact, early colloidal silicas were not commercially useful because they were too unstable and contained only low levels of silica. It wasn't until the production of LUDOX™ in the late 1940's that the applications for colloidal silica began to expand.

 · Colloidal silica can be used for final general metallographic polishing. It is used to polish silicon sin-gle crystals for electronic applications and, subsequently, polycrystalline silicon for ...

Colloidal silica is extensively used as a rheological additive in personal care products to control flowability.
