Method of making high-density sintered metal
Abstract
Abstract A METHOD FOR MAKING HIGH-DENSITY (AT LEAST 90 PERCENT OF THEORETICALLY SOLID) METAL BODIES FROM REDUCIBLE METAL COMPOUNDS WHICH CONSISTS OF EXPOSIN COMPACTED PARTICLES OF SUCH COMPOUNDS, AT LEAST 35 PERCENT (BY WEIGHT) OF WHICH ARE OF LESS THAN 10 MICRONS IS DIAMETER, TO A REDUCING ENVIRONMENT AT A TEMPERATURE WITHIN A RANGE OF FROM THE LOWEST TEMPERATURE OF WHICH REDUCTION WILL TAKE PLACE TO A TEMPERATURE WHERE SINTERING OCCURS AND THEN SUBJECTING SAID POWDERS TO SINTERING. IN A PREFERRED EMBODIMENT OF THE PRESENT INVENTION METAL COMPOUND POWDERS ARE EMPLOYED THAT HAVE A MEAN PARTICLE SIZE NO GREATER THAN 6 MICRONS AND AT LEAST 25 PERCENT OF THE POWDER HAS A PARTICLE SIZE NO GREATER THAN ABOUT 2.5 MICRONS. OPTIMUM RESULTS ARE OBTAINED WHERE THE AVERAGE APPARENT PARTICLE SIZE IS LESS THAN ONE MICRON.
