Abstract (en)
[origin: WO2012020017A1] A process for producing magnetic granular expanded glass comprises the following process steps: - ground glass and magnetic pigments of one or more ferrimagnetic materials are mixed, - said mixture is dispersed to form a first premixture, - at least some of said first premixture is mixed with expanding agent, binder and water to form a homogeneous slurry, - the slurry is granulated using the remnant of the first premixture which possibly remains to form magnetic granular expanded glass green bodies, and - the granular expanded glass green bodies are foamed to form magnetic granular expanded glass particles at temperatures of 600°C to 950°C.
