Silicon nitride membrane window schematics:
Membrane burst pressure:
With the right thickness and size combination, Norcada’s low stress silicon nitride windows can be used as an X-ray window and a barrier between ambient and vacuum. The maximum pressure (burst pressure) a silicon nitride membrane can hold strongly depends on the thickness and size of the membrane. In addition, the burst pressure is much higher when applied on the top side of the membrane window (vacuum on back cavity side). The table below summarizes the membrane burst pressure for different membrane thicknesses and sizes. Pressure value is given in PSI and is measured by applying a positive pressure on the top side of the membrane window.
