A method of synthesizing a phase-change type materials with a stoichiometric composition

摘要

the present invention , Se-Sb-Te, Ge-Sb-Te or the like, a structure having three won in the synthesis method of the phase-change material to be a stoichiometric alloy body by rapidly quenching the melt and the process of mixing powders of each element constituting the alloy, in which the inside to the mixed powders are pressed green form is inserted but use the graphite mold (2) , the interior of the green compact by applying a pulsed direct current in one direction through the graphite mold heat the green compact (P) , and the outside of the green compact , the cooling gas for cooling the green compact Since the formation of the alloy material to flow through the cooling gas passage of the graphite mold , a uniform composition of the synthesized metal compound , and is effective to simplify the synthesis process while increasing the purity .
