Our premium Silfit Z 91 is derived from Sillitin Z 86 through a specialized thermal process. During this process, the crystal water in the kaolinite content is removed, resulting in the formation of new, almost amorphous mineral phases. The silica content remains stable at the applied temperature. The result: products with exceptionally high whiteness and impressive color neutrality – ideal for your application.
All calcined products have a particle size that approaches that of the uncalcined basic material Sillitin Z 86.
The measuring method for this particle size distribution is based on the Fraunhofer analysis of diffraction spectra.
The analyses were performed with a Matersizer 3000, which is a laser device from Malvern Instruments.
With regard to the CIELAB color values L*, a* and in particular b*, the calcined products are significantly brighter and more color neutral than the classic products Sillitin and Aktisil.
