Process for production of ultrafine nickel powder |
摘要 |
In a process for production of ultrafine nickel powder, raw material gas having a partial pressure of nickel chloride vapor within a range from 0.2 to 0.7 is fed into a reducing furnace and the nickel chloride vapor is reduced with hydrogen while flowing the raw material gas in this reducing furnace at a space velocity (SV) within a range from 0.02 to 0.07 sec-1.
