a dry cake which can then be crushed to a powder or to small particles and extruded pelletized or made into forms suitable for its intended use typically materials prepared after mild drying contain the organic template compound and water of hydration within the solid mass and a subsequent activation or calcination procedure is necessary if it is desired to remove this material from the final product typically mildly dried product is calcined at temperatures ranging from about 260 u00b0 to about 850 u00b0 c and preferably about 425 u00b0 to about 600 u00b0 c extreme calcination temperatures or prolonged crystallization times may prove detrimental to the crystal structure or may totally destroy it generally there is no need to raise the calcination temperature beyond about 60 u00b0 c in order to remove organic material from the originally formed crystalline material typically the molecular sieve material is dried in a forced draft oven at 165 u00b0 c for about 16 hours and is then calcined in air in a manner such that the temperature rise does not exceed 125 u00b0 c per hour until a temperature of about 540 u00b0 c is reached calcination at this temperature usually is continued for about 4 to 16 hours a catalytically active material can be placed onto the borosilicate structure either before or after incorporation into a matrix.
