    Abstract: THE PREPARATION OF SOLID CATALYSTS CONTAINING SUCH ADDIA PROCESS FOR PREPARING GLASS FREE OF VOIDS AND IMPERFECTIVES AS METAL TELLURIDES, USEFUL IN OXIDATION PROCESSES TIONS IS PROVIDED COMPRISING CHARGING AN AQUEOUS SLURRY OF FOR OLEFIN CONVERSIONS, WHEREIN SAID CATALYSTS ARE PREGLASS-FORMING METAL HYDROXIDE, AND SAND TO A MOLTEN GLASS POOL PARED BY METHODS WHICH INCLUDE DISPERSING SOLID CATALYST AT A RATE SUFFICIENT TO MINIMIZE SPATTERING SEGREGATION OF REACCOMPONENTS IN A DISPERSING MEDIUM AND REMOVAL OF THE TANTS AND CARRY-OFF OF ALKALI WITH THE EVOLVED STEAM, MAINTAINMEDIUM FORM THE SOLIDS WHILE THEY ARE BEING MIXED OR ING THE TEMPERATURE OF THE MOLTEN GLASS AT OR ABOVE THE FUSION AFTER MIXING, IS IMPROVED BY THE ADDITION OF A SURFACE TEMPERATURE OF THE REACTANTS FOR A TIME SUFFICIENT TO EFFECT ACTIVE AGENT IN THE MIXTURE TO PROMOTE BLENDING AND REACTION, AND RECOVERING THE RESULTING GLASS. IMPROVE THE RESULTING CATALYST.
