mgo wafer | Magnesium Oxide Wafers Substrates

mgo wafer  : Magnesium oxide single crystal is used for magnetic thin film optical films, as well as for mobile communication devices or superconducting devices such as microwave filters. It can obtain a large area of substrate with a diameter of more than two inches, making it an important industrial substrate worldwide. Its loss is also very small.

At present, although there are many suppliers of magnesium oxide in China this year, there are very few who can produce high-quality magnesium oxide gold sources. They need to provide you with two aspects of experience with good and stable performance, and be able to provide products with a wide range of sizes.

At the same time, they need to achieve customized requirements according to the special requirements of customers, which are very strict requirements for manufacturers, At the same time, our large inventory can provide our end users with fast delivery times.

Main advantages and characteristics.

  • The density is indeed depressed.
  • High quality crystal.
  • It can be used to improve the scale of semiconductor manufacturing.
  • The tolerance range applicable to some specific equipment manufacturing requirements.
  • It can optimize the performance and cost control of power electronic equipment.
