MY is a molybdenum-based material which is doped with 0.47 weight% ofY2O3 and 0.08 weight% of Ce2O3. MY is available as ribbon material (ESS-ribbon or standard qualities). Fine-dispersed particles of Y2O3 are responsible for improved mechanical properties as well as a better sealing to quartz glass.

Advantages compared to pure Mo:

• better adhesion to glass melts
• higher recrystallization temperature
• better weldability

Typical areas of application:

• conducting ribbon and sleeves for the lighting industry
• boats and coils for resistive evaporation
