Nitrogen Compounds TRIZ Cases
- cBN Sintered Material With Oxygen-Bonded Grain Interfaces
Controlled oxygen at cBN grain interfaces strengthens WC-Co-Al bonded sintered material, reducing chipping and extending cutting tool life.
- Binder-Free Polycrystalline CBN for Longer Precision Tool Life
Ultrahigh-pressure conversion of hexagonal boron nitride creates binder-free polycrystalline CBN that resists edge wear and extends tool life.
- Polycrystalline CBN Composition for Binder-Free Cutting Edges
Binder-free ultrahigh-pressure CBN sintering improves strength, thermal diffusivity, and edge wear resistance in difficult machining.
- Boron Nitride Polycrystal Sintering for Hardness and Thermal Stability
Preheated high-pressure boron nitride powder is sintered without binders to improve hardness, strength, and thermal stability for tools.
- AlN Dopant Composition for BAW Filter Spurious Wave Suppression
Doping AlN with Be, Sr, or Na suppresses transverse acoustic waves in BAW filters, improving frequency response and reducing signal interference.
- Aluminum Nitride Layer Growth With Local Piezoelectric Control
Patterned metal nitride enables simultaneous AlN growth with piezoelectric and non-piezoelectric regions, balancing resonator function and heat dissipation.
- Scandium Aluminium Nitride Sputtering for Low-Defect RF Films
A two-step pulsed DC reactive sputtering sequence cuts defects in Sc or Y-doped AlN films while preserving texture and coupling for RF resonators.
- Gallium-Doped AlScN Film for Lower Coercive Field Ferroelectrics
Partial gallium substitution in AlScN film raises remanent polarization while lowering coercive electric field for compact, low-power ferroelectric elements.
- Aluminum Nitride Layer Formation With Patterned Orientation Control
A patterned metal nitride layer controls AlN nucleation so one deposition yields piezoelectric regions and non-piezoelectric thermal paths.
- Doped Aluminum Nitride for BAW Resonator Spurious Wave Suppression
Targeted AlN doping suppresses spurious acoustic waves in BAW resonators while improving coupling, quality factor, and frequency response.
