Abstract

<PICT:1066849/C1/1> Silicon particles are compacted by hydrostatic pressure by a method which includes placing the particles in a flexible sleeve 2 which is located within a perforated metal tube 1 and closed by stoppers 4 to one of which a rod 7 is attached. The tube 1 is then placed in a flexible bag 5 which is placed in a cylinder containing glycerine and subjected to pressures in the range 10,000-60,000 p.s.i. The porous compacted mass may be sintered at about 1300 DEG C. Reference is made to particles of 75-150 microns size compressed to a body of density 1.7 grams/c.c.ALSO:Silicon particles are compacted by hydrostatic pressure by a method which includes placing the particles in a flexible sleeve 2 which is located within a perforated metal tube 1 and closed by stoppers 4 to one of which a rod 7 is attached.
