"Diatomaceous earth grades-applications"

Dental impression material

Because of its high water absorption capacity of approximately 200 g/l, our diatomaceous earth products guarantee rapid mixing behaviour of the impression mass and short setting phases.

Paper industry

Diatomaceous earth products with a very high Blue Light Reflectance of approximately 95, high water absorption capacity of > 200 g/l and a surface (BET) of around 2 m²/g are extremely well suited for the use as functional fillers, among other things for the production of decorating paper.

Insecticides

The sharp-edged diatom structures cut their way through the exoskeleton of, for instance, ants which then dry out. Our natural diatomaceous earth grades with a crystalline silica content of < 0.1% are safe for children and pets, too.

Catalyst carriers

Our natural, uncalcined diatomaceous earth products with a low specific content of Al2O3 and Fe2O3 are extremely well suited for the use as catalyst carriers, for instance for nickel, cobalt, copper, sulphuric acid and also for the food industry (fat catalysts).

Refractory industry

Our heat-resistant, very light diatomaceous earth grades with an apparent density of approximately 120-140 g/l are ideal functional fillers for the production of refractory materials, heat insulating boards and fireproof boards.

Centrifugal casting

By means of defined particle distribution with an average size of approximately 8 µ, our readily calcinated diatomaceous earth grades are excellent inert materials for centrifugal casting.
