      Figure 2.28   Detailed view of the extensive material damage cause by the silicon dust explosion at
      Brernanger, Norway, October  1972.


      Figure 2.27 shows the total damage of the entire grinding plant building, and Figure 2.28
      gives a detailed view of the extensive damage.
        Eyewitnesses reported that the flame was very bright, almost white. This is in accor-
      dance with the fact that the temperature of silicon dust flames, like flames of aluminum
      and magnesium dust, is very high due to the large amounts of heat released in the com-
      bustion process per mole of oxygen consumed (see Table 1.1 in Chapter 1). Because of
