Corundum Brown Al2O3
Electrocorundum Brown Al2O3
Brown Fused Aluminium Oxide Al2O3
Chemical name: Al2O3
Grain sizes:Corundum Brown F 12 - F 1200
Packing: 25 kg paper bags on palette (1000 kg)
shrink-wrap or big-bags
Chemical properties: Corundum Brown is loose
material which is acquired by gradual melting reduction of
bauxites in electrical furnace. The basic raw material for
production is calcinated bauxite which progress melting in
temperature higher than 2000 oC.
Usage: Corundum Brown is due to
it ´s characteristic features - high rigidity and hardness -
used where it supposed to be hard mechanical exertion with
whetting, for example while whetting of metals (very hard alloy,
malleable metal, steel) or when grinding of wood. Those features
could be used in production of grinding surfaces, abrasive tools
and instruments and for blasting method.

Company
KORUND
BENÁTKY, s.r.o. was established in 2003 as a
subsidiary company of KOLTEX COLOR, s.r.o. which took over the
plant CARBORUNDUM Electrite, a.s., plant II. - a production of
White Corundum and SiC. Production operation was taken over
including all technology and including long-time employees of
the plant. Production was taken over in full running so that a
continuity of deliveries was not disturbed.In the present time
sorting lines for White Corundum and SiC are operating. Sorting
lines are sat with ball mills, vibrational mills, hammer mills,
forming mills and many different sorting machines. Grain is
during a production several times magnetized. Production process
is permanently checked by production control and internal
laboratory. Every individual storage tank is equiped with exit
confirmation of laboratory.
