Applications

Transparent ceramic combines the high quality of single crystals with the good machinability of glass.

This enables a variety of uses such as:

  1. heat and scratch resistant windows
  2. abrasive resistant technical parts for industry and aerospace
  3. optics, sensors and light converters
  4. wafer for electronics
  5. ballistic armor and protection
  6. design apps, watch industry and jewelry
