Corundum materials containing aluminium oxide Al2O3 95-99.5% are widely used
in many applications. Thanks to its properties (see the table) ceramics
is used as high-voltage and high-frequency insulators, current inputs, device
envelopes, resistance substrates. These products may be soldered in vacuum
using active metals, and after the preliminary metallization by refractory
metals it may be soldered with copper, nickel, covar alloys, navi. Besides
ceramics parts may be soldered with each other and metals by means of fusible
and refractory solder-glass.
Retaining the resistivity at high temperature (700C) allows to use ceramics as
insulators in ignition plugs and retaining rather high strength at heating to
the temperature 1400C, ceramics may be used as desolder nozzles and other gas
burners, insulators in automatic systems of high-temperature furnaces.
High surface hardness (6-70GPa), wear resistance, refractoriness, chemical
resistance predetermined its use as per below:
- refractory “boats” used in metallurgy
- sealing elements in pumps and their operative parts when pumping over
corrosive and abrasive medium
- single and double channel ceramics insulators and jackets of thermocouple
heads
- holders of die holes (earlier manufactured of clinkstone) at work in
corrosive liquids and gases,
- abrading tools
- special thin plates and overlapping up to 400mm in length, 0.6-30mm in
thickness for special applications
- cores used to form hollows in bricks enabling to improve lifetime of
puncheons 5-10 times
- ceramics nozzles of gas burners, burners with Ar arc welding, sandblasting
installations enabling to improve lifetime in comparison with nozzles made of
VK alloy 2-3 times.
