Exercise 8: Selection using a Limit Stage

Filter records by applying limits to one or more attributes.

  1. Select materials with specific thermal and electrical properties.
    1. Create a new Limit Stage with the following criteria:
      Maximum service temperature
      > 200 °C
      Thermal conductivity
      > 25 W/m.°C
      Electrical resistivity
      > 1e15 μohm.cm
    2. Use the limit bars for guidance on suitable values, and keep AND logic selected. Enter the limits – minimum or maximum as appropriate – and click Apply.
    3. You can change the units on the datasheet by going to the Units tab under Settings.

    Example results: Aluminum nitride, Alumina, Silicon nitride.

  2. Filter the results further to select only materials which are resistant to Hydrofluoric Acid (40%).
    1. Under Durability: Acids, select Acceptable and Excellent for Hydrofluoric Acid (40%).
    2. Click Apply. Silicon nitride should be the only passing record.
