<p>A diaphragm for use in the electrolysis of aqueous solutions of ionizable compounds in electrolytic diaphragm cells is comprised of a support fabric impregnated with particles of a siliceous composition having the formula: (X)m(Si)p(O)q(H)r - nH2O wherein x is at least one metal selected from the group consisting of Be, Mg, Ca, Sr, Ba, Ti, Zr, Al, Zn and mixtures thereof; p is a number from 1 to about 16; m is zero to about p; q is a number from 2 to about 5p + r; r is zero to about 4p; and n is zero to about 30. The siliceous compositions are capable of undergoin hydration when in contact with at least one of the ionizable compounds in the electrolytic cell. The support fabric has an electroconductive zone along one side. The diaphragms are physically and chemically stable, provide reduced cell voltages during operation of the cell and have increased operational life.</p> |
