Lanthanum Aluminate 
Applications

LaAlO3 single crystal substrates are commonly used for epitaxial growth of thin films such as high Tc superconductors, magnetic and ferroelectric materials. The dielectric properties of LaAlO3 crystal make it suitable for low loss microwave and dielectric resonance electronics applications.  MSE Supplies can supply a wide range of LaAlO3 single crystals and epi-ready crystal substrates to meet customer's specific requirements. 

Lanthanum Aluminate Packaging

Our lanthanum aluminate is carefully handled to prevent damage during storage and transportation.
