Rate of reactions between D/sub 2/O dand Ca/sub x/Al/sub y/O/sub z/
The rate of the reaction between D/sub 2/O and the calcium aluminum oxides Ca/sub 3/Al/sub 2/O/sub 6/, Ca/sub 5/Al/sub 6/O/sub 14/, CaAl/sub 2/O/sub 4/, and CaAl/sub 4/O/sub 7/ was investigated by on-line neutron diffraction powder methods at temperatures from room temperature to 100/sup 0/C. The rate of the reaction increases with increasing calcium content of the compounds and with increasing temperature for each of the compounds. The crystallographic stable hydrate Ca/sub 3/Al/sub 2/(OD)/sub 12/ is obtained from CaAl/sub 4/O/sub 7/ and CaAl/sub 2/O/sub 4/ at temperatures above 63/sup 0/C, from Ca/sub 5/Al/sub 6/O/sub 14/ at temperatures above 49/sup 0/C, and from Ca/sub 3/Al/sub 2/O/sub 6/ at temperatures as low as 7/sup 0/C.
