Liberation of hydrogen in the roasting of quartz

Brief Communications


  1. 1.

    In the roasting of quartz above 500°, isolated surface OH groups may dissociate with formation of hydrogen. About 10% of the possible limiting content of hydroxyls on the quartz surface dissociates in this way.

  2. 2.

    In the roasting of silica gel under these conditions, only the liberation of water is observed, which is possible only when we assume surface migration of protons.
