- Description:
- The silica nanoparticles are silane derivatized by covalent bonding (a condensation reaction) of the hydrolysed organosilanes to the silanols on the surface of the particles. This is done at high temperature (50-90C) and at high pH (9-11), making all the glycidoxypropyl silanes open up to diols (the functionality introduced on the surface of the Levasil CC products). For the Levasil CC 141, CC301 and CC401 products, the glycidoxypropyl silane is the only silane. For the Levasil CC503, a 50/50 molar ratio of glycidoxypropyl and propyl silane is used. No purification of the products is made.

- Additional information:
- The particle forming mechanism for each manufacturing process starts with the formation of liquid nuclei that grow to constituent particles that coagulate to aggregates and solidify. Constituent particles are therefore spherical in nature while aggregates (and agglomerates) show a high fractal structure.
As shape is spheroidal, Typical lateral dimension 1, Typical lateral dimension 2 are equal to Typical Length . Typical Length is d50 value.
As shape is spheroidal, Typical aspect ration is 1 (the substance is not in fiber form).
