1 Piezoelectric Applications Lithium niobate crystal has high Curie temperature, small temperature coefficient of piezoelectric effect, high electromechanical coupling coefficient, low dielectric loss, stable physical and chemical properties and processing It has good performance and is easy to prepare large size and high quality crystals.
the relationship of SAW substrates between orientation and flat
Lithium Niobate Thin Films on Insulator is kind of POI (Piezoelectric on Insulator) wafer. It's stacked sequence structure is made of support substrates that can be silicon, quartz, fused silica, sapphire or LN wafer, the interlayer is thermal oxide SiO2 that works as insulator and lithium niobate film is the functional layer above the insulation
CQT production line Measurement and inspection methods
Here is High Quality Quartz Materials China Factory talking about Production Process Of Quartz Rods. 1. A damaged layer on the surface of the Fused Silica Wafers due to processing stress after work.2. Use the sandblasting method to feel the lower half of the defects and defects on the wafer.
