XRD evaluation of nickel-phos phorus n anoparticles lattice tensions in vari ous thermal annealing conditions

In many production processes of nanop articles, their controlled growth has important rule. These materials w idely used in production of magnets, catalysts and surfacta nts and ...[۱ ] . In this article we will investigate the heat treat ment conditions of nickel-phosphorus nanoparticles. Knowing these condition s will result saving the time and have economical benefits. In the first, we produced ni ckel phosph orous nano particles and then seek to investigate heat treatment conditions [۲,۳] .Mate rials and m ethods:Certain amount of nickel sulfate dissolved in distilled water. This solution slowly adde d to a soluti on of sodium hypophos phite that its pH fixed t o ۹ and the t emperature must be ۹۰ to ۹۵ °C. R eaction time is ۴۵ to ۵۰ minutes. produced NiP nanoparticles annealed u nder argon gas at temperatures ۱۱۰, ۱۵۰, ۲۵۰, ۴۵۰ ° C, each at ۱, ۲ and ۳ h.
