1. Method for placing sub-millimeter sized particles in a carrier material, wherein the method comprises the following steps:
a.) providing an electrostatic precipitator comprising
a casing having an inlet for inserting a gas flow into the casing and having an outlet for guiding the gas flow out of the casing,
a channel for passing the gas flow from the inlet to the outlet between the inlet and the outlet,
a discharge electrode on a first side of the channel and
a collecting electrode at a second side of at least a part of the channel, the second side being located opposite to the first side such that the electrostatic precipitator is adapted for applying an electric field between the discharge electrode and the collecting electrode,
a receiving volume adjacent to the collecting electrode and between the collecting electrode and at least a part of the channel;
b.) providing the carrier material in the receiving volume, wherein the carrier material is in the form of a molten material, and wherein the carrier material has a melting point which lies above 0° C.;
c.) guiding the sub-millimeter sized particles in the gas flow into the inlet and into the channel;
d.) applying the electric field between the discharge electrode and the collecting electrode such that the sub-millimeter sized particles are guided into the molten material; and
e.) removing the carrier material with embedded sub-millimeter sized particles from the receiving volume.
