Product Description
LaAlO3 Lanthanum Aluminate Crystal High-Temperature Superconducting Substrates
Lanthanum aluminate (LaAlO3) substrate single crystal is the most important industrialized, large-size high-temperature superconducting thin film single crystal substrate material. It is a good substrate material for epitaxial growth of high temperature superconducting thin films and giant magnetic thin films. Its dielectric properties are suitable for low loss microwave and dielectric resonance applications.
Main Advantages:
- Small dielectric constant;
- low dielectric loss;
- good lattice matching;
- small thermal expansion coefficient;
- good chemical stability;
- wide energy gap;
- large specific surface area;
- certain activity;
- good thermal stability
Applications:
- Electronic devices,
- catalysis,
- high-temperature fuel cell,
- ceramics,
- sewage treatment,
- substrate materials
