Technology for production of nanoceramic
article of complex shape.
Nanoceramics Production by Dry Compacting
|
Field of
application
- Electronics (electroceramics: superconducting, ion and metallic
conducting, semiconducting, dielectric, ferroelectric ceramics;
piezoelectric transducers, high-frequency piezoresonators for
teleсommunications; HTSC coils, solenoids, SQUIDs, shields of magnetic
fields, etc.).
- Household appliances (infrared transmitters for remote-control
consoles, etc.).
- Motor, airspace, cable, textile industries; chemical,
petroleum-and-natural gas engineering, construction machine-building
industries (construction parts from high-strength, tough, wearproof,
shockproof, heat-proof, corrosion-proof ceramics: seals, injectors,
unions and spinnerets, wire dies, impellers, etc.).
- Medicine (bioactive, bioinert ceramics for implants; ceramics for
stomatology etc.). |

Main Features of the
Technology
The
technology is in the special ways of dry pressing the products of the complex
shape from dustformed ceramic nanopowders, including the use of ultrasonic
action.

Competitive
advantages
- it allows to manufacture defectless powder products of the all classes of
complexity with uniform density in volume
- considerably improves the quality and performance characteristics of
products (hardness, plasticity, wear-resistance, uniformity of density, physical
properties etc.) due to nanostructure formation in sintered ceramics
- rising economy at the expense of application of standard processing
equipment, reduction of number of technological operations, decreasing power
intensity and labor input of production process |
