molybdenum powder
Molybdenum itself is a demanded and expensive material, the extraction
of which is a very time-consuming process. Molybdenum powder is a finely
dispersed composition with a small presence of impurities, has a gray
color. It is produced by reduction with hydrogen.
Metallurgy using molybdenum is very complex due to its exceptional
refractoriness. Therefore, the metal is first pulverized. Then it is
sent to an electric arc furnace with a consumable electrode. Molybdenum
powder is heated on the surface of each particle, and then compressed
into a finished product. In terms of strength, it is practically not
inferior to a cast sample, but it does not need to spend a lot of money
on its manufacture.
Molybdenum powder may vary depending on the method of application: For
spraying with a plasma apparatus. It is distinguished by the presence of
additives, as well as the optimal particle size for this procedure.
Reduced chemical reaction powder. This is the purest metal that is used
only to control chemical processes.
Compact type powder. It differs from other powders in particles of
different sizes, so it is perfectly optimized. The air content in such a
powder almost tends to zero.
Briquette type powder. It is advantageous for the production of large
parts, because it significantly speeds up the loading of furnace bins.
Also, with its help, it is convenient to dispense without
instrumentation.
Molybdenum powder is obtained from molybdenum anhydride (molybdenum acid
MoO3) by reduction with hydrogen. The conditions of the recovery process
are determined depending on the final destination of the resulting
powder. Molybdenum powder intended for the further manufacture of wire,
rods, sheets and other products should contain 99.9% molybdenum and have
a fine-grained structure. Molybdenum powder, which is used in the
production of steel, should be 99.0-99.5% molybdenum and may have larger
grains.
The purity of the resulting molybdenum powder largely depends on the
purity of the starting MoO3 oxide. It is very important that the
molybdenum oxide contains a small amount of impurities. The grain size
of the obtained powder depends on the reduction conditions and on the
grain size of the molybdenum oxide. As a rule, the molybdenum powder is
obtained the larger, the larger the grain size of the original
molybdenum acid. The temperature at which molybdenum is reduced and the
concentration of water vapor also affect the grain size. The average
grain size of the molybdenum powder increases with increasing recovery
temperature. By selecting the appropriate reduction conditions and MoO3
molybdenum anhydride, it is possible to obtain molybdenum powder with an
average grain size of 0.5 to 10 microns or more.
Molybdenum powder has a number of positive qualities that are necessary
in various industries. This is not only its high melting point (heat
resistance), but also its wear resistance and corrosion resistance. It
also has good acid resistance.
