A Confocal Laser Scanning Microscope (CLSM) in combination with an
infrared furnace is used for in-situ observation of microstructure
evolution in solid metals.

The oxygen potential of a slag affects its reactivity with the metal,
the matte and the lining of the reactor. Therefore, an accurate
measurement of the oxygen potential is important to the product quality
as well as the process efficiency.
The purpose of this project was to find out whether the RapidoxTM from
Heraeus Electro-Nite, originally
developed for measuring the pO2 of molten glass,can be used to obtain
the pO2 of molten metal slacs. Measurements for different metal slacs
from non-ferrous pyrometallurgical processes and covering a wide range
of pO2 values were carried out. The influence of temperature, atmosphere
and composition of the slacs was also studied.
Magnetic hysteresis curves for various CoNiFe-alloys, prepared by
electro-deposition, were obtained using a measurement technique based on the
Magneto Optical Kerr Effect. These alloys can be used in recording heads for
