Claim 1
Independent Claim
130 words
A METHOD FOR PREPARING A BINARY COMPOUND BY THE DIRECT COMBINATION OF EXOTHERMIC REACTING ELEMENTS, SAID COMPOUND HAVING A MELTING POINT TEMPERATURE SIGNIFICANTLY HIGHER THAN ITS CONSTITUENT ELEMENTS, AND BEING RELATIVELY INSOLUBLE IN A SOLUTION OF ITS CONSTITUENT ELEMENTS AND IS FORMED AT A TEMPERATURE BELOW ITS MELTING POINT TEMPERATURE, COMPRISING THE STEPS OF: (A) COMMINUTING THE REACTING ELEMENTS, WITH THE HIGHER MELTING POINT TEMPERATURE ELEMENT BEING COMMINUTED TO A PARTICLE SIZE OF NO GRETER THAN 44 MICRONS, (B) MIXING THE COMMINUTED ELEMENTS, (C) INSERTING THE MIXTURE INTO AN AMPOULE, (D) HEATING THE MIXTURE AT A RATE OF FROM ABOUT 0.1* C. PER MINUTE TO 5*C. PER MINUTE, TO A TEMPERATURE OF ABOUT THE MELTING POINT TEMPERATURE OF THE HIGHER MELTING ELEMENT AT WHICH TEMPERATURE THE REACTION GOES TO COMPLETION.
