6Inch Dia 150 Mm Lithium Tantalate Wafers LiTaO3 LiNbO3 Hexagonal Crystal Structure
BonTek Optoelectronics manufactures high purity single crystal Lithium Tantalate Wafers for optoelectronics applications. Our standard wafer diameters range from 25.4 mm (1 inch) to 150 mm (6 inches) in size. Lithium Tantalate (LiTaO3), also known as LN crystal, is a kind of typical multifunction crystal material. Lithium tantalate wafer has both chemical and mechanical stability as well as a high optical damage threshold. These properties make LiTaO3 Wafers useful for SAW (surface acoustic wave) devices and optical uses.

FAQs:
- Q: What are the products you mainly work on?
A: We look at ourselves as the piezo wafer specialist. We are the very first to work with Single Crystal Quartz in China about 30 years ago. Then gradually we step in the field of LiNbO3, LiTaO3, Quartz glass, LGS, CTGS etc. Especially, if you are looking for a piezo quartz supplier, we are the ultimate choice! We export millions of quartz blanks each year because we master the AT, SC and IT cuts with superior angle precision.
- Q: Can you accept product customization?
A: Yes, of course. We can fabricate as per your request. In addition, we are so experienced with piezo wafers that we can provide you relevant suggestions if you are not 100% sure about your choice. Besides, we do have some standard wafers in stock, please check with us.
- Q: Can you deliver the goods via our courier agent?
A: Yes, we would suggest you go with the courier agent you are most familiar with (DHL, FedEX, UPS etc.). We can ship via your account. And, of course, we will pack the products safely in acceptable size to help you save the shipping cost. If you need us to take care of the freight, it’s also not a problem. We also have good discount with the international courier companies.
- Q: How can you guarantee we get what we want safely?
A: The wafer products are fragile and sometimes expensive. The last thing, as the manufacturer, we want to see is the products we make were damaged during courier. As a result, we will pack the wafers adequately and put them in a proper carton filled with buffer sponge. However, accidents are inevitable sometimes. So, please follow the “Acceptance check” steps shown in the drawings below. If the unwanted happened, we will either give the replenishment or refund if you follow the checking steps.
