text: Three compositions were made from a sea water periclase sized so that substantially all passed a 6 mesh screen and about 30% passed a 100 mesh screen, and having the following typical chemical composition: 2.1% SiO 2 , 1.1% CaO, 0.4% Fe 2 O 3 , 0.3% Al 2 O 3 , 0.3% Cr 2 O 3 , and (by difference) 95.8% MgO. The first composition (A) was bonded with 0.8% hydrated aluminum sulfate (Al 2 (SO 4 ) 3 .14 H 2 O) and 0.6% citric acid, both percentages being based on the total weight of the composition.
