Alkali metal alumino silicates,methods for their production and compositions thereof

Abstract

Abstract THE SUBJECT MATTER OF THE FOLLOWING SPECIFICATION CONCERNS THE PRODUCTION OF FINELY DIVIDED MATERIALS USEFUL AS PIGMENTS, MOISTURE CONDITIONERS, PAPER FILLERS, AND IN RUBBER REINFORCEMENT AND THE LIKE. CONSIDERING PRESENT ECONOMICS, PERHAPS THE MOST PRACTICAL EMBODIMENT OF THE SUBJECT MATTER EMPLOYS THE REACTION OF A SOLUBLE SODIUM SILICATE AND ALUMINUM SULFATE IN PRODUCING PRECIPITATES COMMONLY KNOWN AND IDENTIFIABLE AS SODIUM ALUMINO SILICATES, THE PRECIPITATE BEING ULTIMATELY COLLECTED AS A DRIED PARTICULATE MATERIAL OF SUB-MICRON PARTICLE SIZE. THE DISCLOSED PROCESS INVOLVES CONDUCTING THIS GENERAL TYPE OF REACTION IN THE PRESENCE OF CALCULATED QUANTITY OF SODIUM SULFATE FROM THE OUTSET OF THE REACTION WHEREBY ECONOMICS ARE IMPROVED AND HIGHLY REFINED MODIFICATIONS IN THE CHARACTERISTIC OF THE FINAL MATERIALS BECOME OBTAINABLE. THE REACTION MAY BE VARIED ACCORDING TO SEVERAL CONDITIONS, SUCH AS PH, TEMPERATURE, CONCENTRATION, MANNER OF FEEDING MATERIALS AND THE LIKE WHEREBY TO BETTER ADAPT THE NEW MATERIALS TO HIGHLY SPECIALIZED NEEDS, SUCH AS IN RUBBER COMPOUNDING AND PAPER PRODUCTION.
