摘要:
Formulation comprising a polymerizable monomer and/or a polymer and, dispersed therein, a superparamagnetic powder, which comprises aggregated primary particles, the primary particles being built up from magnetic metal oxide domains having a diameter of from 2 to 100 nm in a nonmagnetic metal oxide or metalloid oxide matrix. Process for heating the formulation in a magnetic or electromagnetic alternating field. Use of the formulation as an adhesive composition.

摘要:
A dispersion of pyrogenically produced cerium oxide, which does not contain any particles larger than 1 μm, is produced by dispersing a pyrogenically produced cerium oxide in water by means of a dissolver, centrifuging it, separating the supernatant from the bottom product, and again dispersing the supernatant by means of ultrasound. The dispersion can be used for chemical-mechanical polishing (CMP).
