      A novel calcium hydroxide molecular composite: preparation and characterisation 

      Gray, A. C.; Theocharis, Charis R. (1990)
      The surface of a highly crystalline calcium hydroxide sample consisting of thin hexagonal plates was modified by a two-step reaction, so that the majority of surface OH groups were replaced by nitrobenzamide silane groups. ...
