Manufacture of high temperature insulating materials

Claim 1

THE METHOD OF MAKING BONDED THERMAL INSULATION WHICH COMPRISES FORMING IN A 3 DEG. BAUNE WATER SOLUTION OF CALCIUM CHLORIDE A SLURRY OF POURABLE CONSISTENCY CONTAINING MINOR AMOUNTS OF LIME AND DIATOMACEOUS EARTH AND A MAJOR AMOUNT OF GRANULES EXPANDED PERLITE OF GENERALLY SPHERICAL SHAPE AND CHARACTERIZED BY ABSENCE OF CONTINUOUS CAPILLARY SPACES IN A MASS OF GRANULES, NO SUBSTANTIAL AMOUNT OF SAID GRANULES BEING SMALLER THAN 5 MICRONS IN SIZE, WHEREBY WHEN MOLDED THE INTERSTICES BETWEEN THE GRANULES PERMIT READY DE-WATERING AND RETAIN INSUFFICIENT WATER TO CAUSE SHRINKAGE IN DRYING, FORMING AND REMOVING THE WATER EXCEPT A SMALL AMOUNT ADHERING TO THE SURFACES OF THE GRANULES, AND THEN SUBJECTING THE FORMED MATERIAL TO HEAT NOT SUBSTANTIALLY EXCEEDING 600 DEG. F. TO INDUCE REACTION BETWEEN THE LINE, PERLITE AND DIATOMACEOUS EARTH IN THE PRESENCE OF THE WATER ADHERING TO THE GRANULES TO FORM BONDING SUBSTANCES TO BOND SAID GRANULES TOGETHER; THE WATER REMAINING IN THE MASS AFTER FORMING BEING UNABLE TO MIGRATE READILY TO THE SURFACE THROUGH SAID INTERSTICES, WHEREBY IT REMAINS DISTRIBUTED THROUGHOUT THE MASS FOR SAID REACTION, AND THEN CONTINUING HEATING TO DRIVE OFF UNCOMBINED WATER.
