Abstract
1501445 Porous bodies CORNING GLASS WORKS 6 Feb 1975 [8 Feb 1974] 5068/75 Heading C1A A method of making a porous silica-containing body exhibiting a compressive strength greater than 50 p.s.i., having a pore diameter ranging from 100 Š to 1 micron, and wherein at least 80% of the pores therein fall within Œ30% of the average pore diameter value comprises: (a) providing solutions having apH of from 10 to 15 and containing from 1 to 12 moles SiO 2 /litre in solution from silicate solutions selected from lithium polysilicate, sodium silicate, potassium silicate, quaternary ammonium silicate and colloidal silica; (b) combining the said solutions in one of the indicated proper proportions equivalent to: (A) a weight ratio of from 19:1 to 1:4 potassium silicate solution to colloidal silica solution, wherein the said potassium silicate solution consists essentially of 8À3% K 2 O, 20À8% SiO 2 , balance H 2 O and the said colloidal silica solution consists essentially of 40% SiO 2 , balance H 2 O; (B) a weight ratio of from 1:9 to 1:3 sodium silicate solution to colloidal silica solution, wherein the said sodium silicate solution consists essentially of 6À8% Na 2 O, 25À3% SiO 2 , balance H 2 O and the colloidal silica solution is that defined in (A); (C) a weight ratio of from 9:1 to 1:4 potassium silicate solution and/or sodium silicate solution to quaternary ammonium silicate solution, wherein the said potassium silicate solution is that defined in (A), the said sodium silicate solution is that defined in (B), and the said quaternary ammonium silicate solution consists essentially of 9À9% quaternary ammonium ions, 45% SiO 2 , balance H 2 O; (D) a weight ratio of from 19:1 to 1:4 potassium silicate solution and/or sodium silicate solution to lithium polysilicate solution, wherein the said potassium silicate solution is that defined in (A), the said sodium silicate solution is that defined in (B), and the said lithium polysilicate solution consists essentially of 2À1% Li 2 O, 20% SiO 2 , balance H 2 O; in the absence of other oxide species soluble in the solutions; (c) reacting an organic compound therewith selected from formaldehyde, paraformaldehyde, formamide, glyoxal, methyl formate, ethyl formate, methyl acetate, ethyl acetate, and mixtures thereof, at a temperature of from the freezing point to the boiling point of the solution for a sufficient period of time to polymerize the silica into a coherent, porous gelled body and; (d) leaching the said gelled body with a weakly acid solution. The body may also contain up to 70% by weight of an unreactive particulate material passing a 200 U.S. Standard Sieve selected from Alumina, Titania, Zirconia, Carbon, Silicon Carbide, Silicon Nitride, Iron Oxides and catalytically active transition metal oxides, or carbon-containing materials, preferably colloidal carbon, which are subsequently burnt out in a firing step at 600-800‹ C.
