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 揵oats?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.
