What is silica (and what are the differences between the

Silica is the common name for silicon dioxide (SiO 2).In German, it is often called "Kieselsure" (silicic acid). SiO 2 is very common in nature, it gives plants like field horsetail and grass its stability, for example. Evonik produces only synthetic amorphous silica, or SAS.

Milling KNO3

Aug 30, 2021Milling KNO3 - posted in Pyrotechnics: I decided to mill some KNO3 in my ball mill to get fine powder for later use, so that I would not have to powder it in a mortar every time I need it, and I got some really surprising results. I got no powder at all, instead, all of the KNO3 had turned into rock hard balls with sizes ranging from grape size to almost golf ball size.

Generally, silica grades that are used as flow and anti-caking agents have very fine particles. They ensure that powders can flow evenly and do not clump together. As opposed to this, carrier silica types are used to absorb liquids and make them powdery. These

Agglomerate behaviour of fluticasone propionate within dry

After mixing with a carrier, Lactohale LH200, the most cohesive batch of FP, generates a lower fine particle fraction. It can be explained by the fact that agglomerates of fluticasone propionate with very large size was detected in the mixtures. By using silica-gel beads as ball-milling agent during the mixing process, the FP agglomerate size

The Use of Engineered Silica to Enhance Coatings

The addition of 5% silica did slightly reduce gloss, but the silica significantly improved scratch resistance. Results in Figure 10 show three variants of DDS-treated structure-modified silica. Variant 1 is the original that requires milling, variant 2 the same DDS structure modified silica pre-dispersed in methoxypropyl acetate (MPA), and

Mechanical Milling

Moreover, the milling tools should be cleaned and kept inside vacuum-silica gel dissectors in order to protect them from any expected contamination by the dust. Such storing conditions offer prefect protection against corrosion for the steel-based milling tools.-The type of the ball mill used should be considered as an important factor.
