    Abstract: The invention concerns a method for controlling coalescence of particles forming a structure subjected to a treatment designed to establish crosslinking between said particles. The method consists in recording at least a physical quantity, whereof the evolution is continuously measurable and whereto the particle crosslinking is correlated, and in stopping the treatment when said physical quantity reaches a value corresponding the desired coalescence. The invention is characterized in that it consists in measuring as said physical quantity the shrinking of said structure. The invention also concerns a method and a device for making a structure of mutually crosslinked particles using said control method and a method for obtaining a product with interconnected pores, in particular for bone substitution, using such a structure.

    Abstract: A method and apparatus for the cross-hole pressing of cutting inserts is disclosed whereby a green part is fabricated using metallurgical powder and an opening is imparted within the green part by placing the metallurgical powder about an oval-shaped core rod. Using a press with a uni-axial press motion, a core rod is placed within the cavity of a mold and metallurgical powder placed around the core rod and thereafter compressed to form a green part. The subject invention is also directed to an article formed utilizing such a process and the uni-axial press used to produce such an insert.
