Molybdenum glass melting electrodes surface showing the bright
silver-white metal color, placed at room temperature in air, will turn
dark silver or uniform gray. The higher the purity of molybdenum
electrodes the colors look better and smaller annual variation.
Molybdenum electrodes according to the processing methods can be divided
into: polished molybdenum electrode, ground molybdenum electrode and
caustic wash molybdenum electrodes. Molybdenum electrodes after polished
the surface will show rendering brown or dark brown color, but this is
not the color of molybdenum oxide, which is the color of impurities
comprehensive oxides in molybdenum. The light brown color showing the
surface uniformity is better, and then the quality is high. Conversely,
if the surface is black, and different shades of color, then the poor
quality of the electrode. Good quality molybdenum electrodes work in
glass melting furnace for a few months the surface remaining silvery
white color.
