Magnesium fluoride (MgF2) ceramic Dome

Features of MgF2 Ceramic Dome

MgF2 ceramic domes have the following main characteristics:

• High Transmission Performance: They exhibit high transmittance in both ultraviolet and infrared bands, especially in the 3-6.5 μm

  infrared band, with a transmittance of approximately 90%.

• Good Mechanical Properties: They have high hardness (Mohs hardness of 6) and flexural strength (100 MPa), making them

  suitable for use in harsh environments.

• Thermal Stability: They maintain good transmission performance at high temperatures, making them suitable

  for high-temperature environments.

• Chemical Stability: They are insoluble in water and alcohol, slightly soluble in dilute acids, and soluble in nitric acid,

  demonstrating good chemical stability.
