Product Details

Good Thermal Stability Optical Substrate Single Crystal LaO

 

LaAlO3 is a high temperature superconducting single crystal substrate. 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.

Crystro has a professional team with more than 15 years of production experience,we invests heavily in crystal R&D every year to improve products performance and develope new crystals.
