Prolonged immersion in seawater results in chemical alteration of ceramics. This interaction primarily involves some earth alkalis. In the first experiment (six years duration), a powdered calcareous ceramic lost up to one-third of its calcium, gained an equivalent molar proportion of magnesium, and lost some of its strontium. XRD analyses showed it is free calcium phase (CaCO;, Ca (OH)= or CaO) that disappears, and that Mg= CO|(OH):'5H= O is formed. A second experiment, two months of contact with seawater for fired synthetic mixtures of ...
