Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
123 words
IN THE SYNTHESIS OF DIAMOND IN A REACTION CHAMBER IN A HIGH PRESSURE HIGH TEMPERATURE APPARATUS WHICH INCLUDES SUBJECTING A COMBINATION OF A NON-DIAMOND FORM OF CARBON AND A DIAMOND CATALYTIC MATERIAL TO SUFFICIENTLY HIGH PRESSURES AND HIGH TEMPERATURES TO OBTAIN A TRANSITION FROM THE NON-DIAMOND FORM OF CARBON TO DIAMOND, THE PROCESS COMPRISING POSITIONING A PLURALITY OF LAMINA OF NON-DIAMOND CARBON IN SAID REACTION CHAMBER, POSITIONING A PLURALITY OF DIAMOND CATALYTIC MATERIAL LAMINA IN SAID REACTION CHAMBER, ARRANGING SAID CATALYST AND SAID CARBON LAMINA IN ALTERNATE LAMINAR RELATIONSHIP, SUBJECTING SAID COMBINATION OF NON-DIAMOND CARBON AND DIAMOND CATALYTIC MATERIAL TO A COMBINED PRESSURE AND TEMPERATURE IN THE REACTION CHAMBER SUFFICIENT TO CAUSE DIAMOND GROWTH FROM SAID NON-DIAMOND CARBON, AND RECOVERING THE DIAMONDS FORMED.
Claim 2
Dependent Claim
