Procedure

The compositions of the sodium aluminate and the sodium silicate may be varied as desired; however, they should be such as to provide a system having a composition of (3.0-5.5) Na2O2Al2O3.(2.5-4.5)SiO2.(100-120)H2O. For example, a sodium aluminate solution comprising 9.55 percent sodium and 4.48 percent aluminum and a sodium silicate solution of water, sodium hydroxide and sodium silicate of 9.85 percent sodium and 11.90 percent silicon have produced excellent yields.
