Claim 1
Independent Claim
113 words
A PROCESS OF BINDING PARTICLES OF A CERAMIC MATERIAL TOGETHER WHICH CONSISTS ESSENTIALLY IN MIXING PARTICLES OF A CERAMIC MATERIAL WITH AN AQUEOUS SILICA SOL HAVING AT LEAST 5% SIO2, A CONDUCTIVELY OF ATLEAST 1800 MICROMHOS, A WEIGHT RATIO OF SIO2 TO ALKALI METAL OXIDE, CALCULATED AS NA2O, WITHIN THE RANGE OF 160:1 TO 330:1, A PH OF FROM 8.4 TO 10, A RELATIVE VISCOSITY, MEASURED AT 77*F., OF ABOUT 1.5 TO 3.0 CENTIPOISES, AND A SPECIFIC GRAVITY OF AT LEAST 1.047 AT 68*F., ADDING TO SAID MIXTURE AN AMOUNT OF AN ELECTROLYTE SUFFICIENT TO PRODUCE UNIFORM CONTROLLED GELATION OF THE SILICA SOL, SETTING UP THE RESULTANT MIXTURE AND FIRING THE RESULTANT PRODUCT.
