Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
36 words
A METHOD OF MAKING SYNTHETIC NON-HYDROXYL MICA, COMPRISING THE STEPS OF DISSOLVING NON-HYDROXYL MICA FORMING MATERIAL IN HEATED SODIUM META-BORATE GLASS AND THEN COOLING THE RESULTING SOLUTION TO CAUSE SAID MICA TO PRECIPITATE OUT THE SOLUTION.
Claim 2
Independent Claim
36 words
A METHOD OF MAKING SYNTHETIC NON-HYDROXYL MICA, COMPRISING THE STEPS OF DISSOLVING NON-HYDROXYL MICA FORMING MATERIAL IN HEATED SODIUM META-BORATE GLASS AND THEN COOLING THE RESULTING SOLUTION TO CAUSE SAID MICA TO PRECIPITATE OUT THE SOLUTION.
Claim 3
Independent Claim
112 words
A METHOD OF MAKING CERAMOPLASTIC MATERIAL COMPRISING THE STEPS OF DISSOLVING AT LEAST 30% BY WEIGHT OF RAW MATERIAL WHICH CONTAIN THE IONIC CONSTITUENTS OF NON-HYDROXYL MICA IN SUBSTANTIALLY CORRECT STOICHIOMETRIC PROPORTIONS IN SODIUM META-BORATE GLASS HEATED TO A TEMPERATURE BETWEEN ABOUT 1100*C. AND 1250*C., COOLING SAID SOLUTION AT A RATE TO CAUSE THE MICA TO PRECIPITATE OUT AND TO THEN CAUSE THE GLASS TO BECOME A SOLID MASS WITH THE PRECIPITATED MICA SIDPERSED THERETHROUGHOUT, GRINDING SAID MASS, COMPRESSING AT LEAST A PORTION OF SAID GROUND MATERIAL INTO A PREFORM, AND THEN HEATING SAID PREFORM TO CAUSE SAID GLASS TO SOFTEN AND FORM A SUBSTANTIALLY CONTINUOUS MATRIX FOR THE MICA DISPERSED THERETHROUGHOUT.
