Piezoelectric Crystal Lithium Tantalate LT LiTaO3 crystals
Lithium Tantalate (LT, LiTaO3) has unique properties, which as a material finds uses in Electro-Optical and Acousto-Optical applications. These can be : surface acoustic wave devices, bulk acoustic wave devices, piezo-electric transducers and piezoelectric sensors.The 36° and 42 ° cuts of Lithium Tantalate have shown widespread adoption for the telecommunications mobile phone handset market at frequencies from 800 to 2100 MHz. These orientations show an optimized bandwidth / insertion loss trade off in performance and are dominating the ever expanding mobile handset sales.

Q1. Is your company a factory or trade company?
We have a factory and we also do export by ourself trading company .
We are the Sapphire substrates manufactuer and also can produce many type crystal into wafers.
Q2. Could you supply sample?
Yes,we can supply sample according to customer's requirement.
Q3. Do you have any stock of wafer or ingots?
We process many size wafer and lens according to customer requirement.
almost 3inch ,4inch standard thickness wafers is in stock.
So we have few size in stock if it's commen specification.
Q4.Where is your company located?
Our company located in shanghai,China. factory is in wuxi city.
Q5. How long will take to get the products?
Generally it will take 1-3 weeks to process,standard wafer size common can be deliveried in 2weeks
if customized size It is depend on the quantity and the size of the products.
