BASF's carbonyl iron powder to improve electrical components for smartphones and tablet |
|
|
|
(BASF) -- High-purity carbonyl
iron powder (CIP) from BASF contributes decisively to solving the problem of
different voltage: incorporated in the cores of high frequency coils it makes
sure that the current flowing into the sensitive electronics always has exactly
the required voltage.

"With our decades of experience in synthesizing CIP, we can precisely
control the structure of the iron particles and thus their electromagnetic
properties to create an optimal material, thereby making even very small
high-frequency coils extremely efficient," emphasizes Dr. Frank Prechtl,
Business Manager at BASF. "Every tablet PC contains three or four of these
high-frequency coils with CIP core, and a notebook has as many as
ten."

CIP is produced from normal scrap iron, which is finely ground and
reacted with carbon monoxide at increased temperatures under high
pressure. CIP differs markedly from iron powders manufactured using other
techniques, such as electrolytic processes or spray methods. This is the
decisive factor for many applications - for example, the perfect spherical
shape of the CIP particles in the coil cores allows them to be packed together
particularly tightly and the wires of the coil are
